There is no 'typical' session plan, as each athlete is different and has very specific individual needs. After an initial meeting to determine your personal needs and goals, we will meet for either a combined swimming, biking or running workout, or focus solely on one of these individual sports. The session may focus on a combination of technique, or largely on developing your goal race speed. For example, if you are struggling with your goal running pace after the bike, we would focus on bike-run brick sessions with a significant amount of running at race pace or faster. You may be injury prone, and need to work on core work. During the race season we will go over transition specifics and focus on fine-tuning your muscle groups between one discipline to another.

Awesome job

Coach Medena was really energetic, fun, and good with my 15 year old son. She gave honest feedback and provided him with tools he could use on his own to improve his functional strength which will in turn help improve his running. Thanks very much!

Coach Medena has exceeded my expectations--and then some! Medena is a top-notch coach, and her experience is unparalleled. The feedback and training plans she has given me over the past few months have led to real results. I've broken out of my training plateau! I'm so glad to have found her through CoachUp. I recommend her without hesitation, and I plan to keep working with her well into the future. If you're considering enlisting the help of a coach but are feeling unsure, know that you can't go wrong booking a session with Medena. It's more than worth it.

I had a terrific virtual coaching session with Medena. I had sent her short video clips of my stroke and during our virtual session she gave me specific drills to correct technical flaws. A virtual coaching session with Medena is well worth it!

Coach Medena quickly identified suitable areas to work on, and drills to help improve. I would definitely recommend her!

Medena was great! She was knowledgeable and friendly. I can't wait for my next session.

Coach Medena was knowledgeable and a great communicator. She was able to evaluate my run and provide excellent direction. I left the session feeling confident and eager to work on my running form as I train for my first marathon. She also sent a follow up email to remind me of all we had covered during the session. Highly recommend!

Coach Medena is great, warm, and approachable. After just a few minutes in the first session, she spotted the areas that my son needs to improve right away and gave him techniques in order to swim well in the upcoming competition. We wish we had found her earlier! We will book more sessions with her!

Medena is great! She was very kind, patient and fun! My daughter just had a session with Medena & she loved her!!!!! We definitely recommend Medena to those looking to improve their swimming skills. She is a very easy going person & an awesome coach.

I loved my session with Coach Medena. I definitely took away new skills and look forward to another session.

My first half-Ironman is approaching, and I was looking for a swimming instructor who specialized in distance freestyle to improve my technique prior to the race. My stroke needs a lot of work, and I was fortunate enough to find Coach Medena. After 1 minute in the pool, she had already diagnosed the major discrepancies in my stroke. We immediately began working on the drills necessary for me to correct them. After each session, I made instant improvements. Most importantly, Coach Medena gave me the tools to continue bettering my technique on my own, so by the time my next session came around, I was a notably improved swimmer. With my third lesson complete, I have already surpassed my swimming expectations, and my race is still over a month away! Coach Medena is enthusiastic, incredibly knowledgeable, and makes becoming a better swimmer fun. She listened to my feedback, despite me not being the expert, and would adjust our lesson accordingly to target the areas of my stroke I was unsure about. Thanks to what she has taught me, I will continue to improve as a swimmer on my own, as I now have the drills and understanding necessary to make corrections to my own technique. Anyone can become a better swimmer by taking lessons with Coach Medena, no matter their goals. There is no one I could recommend more highly. I look forward to additional lessons with her in the future to fine tune my already vastly improved stroke!

Madena exceeded my expectations of a swim coach. I have always had a fear of drowning and even getting my face in the water. She was really patient and gave me some swimming tips to help with my technique. I would highly recommend her. Thanks Madena!

Good coach!

I've only had one lesson so far, but Coach Medena could see right away where I needed to improve & gave me drills to perform and things to think about when I'm swimming. She is a patient coach & I'm looking forward to learning more from her

Medena is amazing! Her workouts are so efficient and I highly recommend her!

Medena is fantastic! I can swim, but as I started thinking about my first triathalon, I knew I had to work on my freestyle. Medena helped immensely to improve my body position, stroke efficiency, and breathing. She also gave me drills to supplement my swim workouts. After only one session, I could feel tremendous improvement in my overall form. Highly recommend!!!!!!

Coach Medena is an excellent coach. I could barely swim. She improved my swimming in our first session. Anyone in need of a swimming coach should definitely hire her.

Coach Medena is great! She is working with me to create a rehabilitative swimming program. I have a chronic form of debilitating arthritis, and my doctor recommended swimming as part of my therapy. After one visit she helped me improve my stroke and come up with some drills that work for me. Thank you Coach Medena!

Medena was a great choice.
She was friendly and knowledgeable and quickly made me feel comfortable with new techniques. I look forward to further sessions and applying what I have learned.

My daughter had one session with Coach Medena and we saw an improvement shortly after. She had her session and put what she had learned into action all week long during practice at her swim club. My 10 year old daughter was really excited to meet her and was very happy after the session. Coach was very patient with her. Madena helped her with her freestyle and her butterfly stroke. When my daughter had 2 swim meets later that weekend, she took time off of her butterfly and finished nearly 2/3rd of the pool's length ahead of the other kids! Needless to say that we were very happy and proud with her results! This is the time of year when she has sectional, regional, and national swim meets over the next 4 months. We WILL be seeing Coach Medena again!

Coach Medena was great! After one session she was able to clearly explain (in not too complicated terms) what I needed to "fix" my stroke..she didn't make it too complicated, but left me with 2 things to work on and I am looking forward to my next session with her.

Earlier this year I signed up for a half ironman race (my first ever triathlon) and with 11 months to prepare I reached out to Medena to work on the swim. Certainly, leaving myself almost a year was a smart decision, but getting in touch with Medena was an even better decision. With effectively zero swimming background, I was admittedly very intimidated by the 1.2 mile swim. In our first session Medena and I discussed my expectations/concerns in depth, including my intimidation around the swim, and then got right to evaluating my stroke. I have been working with her once a week ever since, making small strides each session and my only complaint is that I wish she could be there EVERY time I got in the pool. To say she has been helpful would be grossly understated. She is super positive, knowledgeable, professional, pleasant and a tremendous listener; everything I was looking for in a coach. I was worried I wasn't ready for a dedicated triathlon coach, but I couldn't have been more wrong. I would highly recommend her for those new to the sport of triathlon, triathletes with a base of experience looking to take their training to the next level and any of those somewhere in between. Needless to say, I will be scheduling her to work on the bike and run next.

Medena is an awesome coach. Very patient, knowledgeable, and super responsive when I have questions! Would definitely recommend!

Coach Medena is a great swim coach. She is patient and explains steps very well.

Medena was awesome, I couldn't imagine a better coach for swimming and/or triathlon training. She consistently focused on the things we thought (and also those that we didn't think of!) we needed to improve on and designed drills specifically for those weaknesses. We did a group session of swims and we plan on continuing!

Coach Medena is a great coach and motivator who makes lessons both fun and challenging. She has the ability to analyze your current swim level and work lessons around both your strengths and weaknesses.

Medena did a great job of helping me improve my swimming. She gave practical tips and drills that helped me improve with each session. Her positive attitude and encouragement also makes it fun. Thank you!

coach medena was fun and professional during a one hour swim lesson. She gave me MANY pointers to focus on during my work outs. I will definitely take more sessions and recommend her to anyone that wants to improve their swimming.

Coach Medena was excellent! She worked with my daughter to improve her swimming and diving skills! She helped her achieve all of her goals and we will booking future sessions with her. Medena is very kind, patience and supportive in coaching. I highly recommend her.

Coach Medena is a fantastic Coach. After just a few sessions, I feel like a more experienced swimmer and ready to take on my first sprint triathlon. I would HIGHLY recommend Coach Medena to anyone.

Coach Medena was a pleasure to work with and an excellent coach. She quickly picked up on our different skill level and got us working a progression of drills that led to a significant improvement for both of us. In addition to her excellent coaching, she was also a pleasure to work with on scheduling (2 person lesson can be a challenge) and helped answer many other tri related questions we had as novice triathletes.

Coach Medena was very helpful in my introductory lesson. She listened to what my personal goals were and helped advise me on specific drills and exercises to improve my form. I feel like I actually 'get' what good form feels like!

Most people assume that you just know how to run naturally - I certainly did! But just one session with Medena revealed some very helpful insight into my posture and cadence that could go a long way to improving my running. After analyzing my form, she immediately had drills and exercises that are already having an impact for me. Medena is positive and supportive and very knowledgable about many aspects of running. I’m looking forward to future sessions and the PRs that her help will yield this fall!

Medena is a wonderful coach! After only one session of working on drills and strength exercises, I already feel like my running form has improved significantly. Not only is Medena very knowledgable about running, but she is also great at translating her knowledge to those she coaches, making the information easily accessible and fun to learn. Medena's thoughtful feedback and enthusiastic encouragement makes her a great coach, and I would definitely recommend her to anyone looking to improve their running.

Medena worked with my 16 year old daughter, who is a Division I high school varsity swimmer, and who swims in USA competitions. She is very serious about swimming and hopes to swim in college. Medena’s worked with her on swim technique, starts and turns. Her enthusiasm and ability to communicate with a 16 year old was tremendous. I believe she has a great deal of intricate knowledge about the sport of woman’s swimming and my daughter found the workout quite helpful, as she gained some new ideas about technical aspects of a sport that she has been involved in for over 6+ years. I would highly recommend Medena to any athlete or parent, who is looking to have their daughter obtain some valuable knowledge relative to the sport of swimming.

I've had several sessions with Coach Medena now and she's been extremely helpful. I was interested in improving my running technique and form, and also getting faster. Medena has helped me through various drills and exercises both to improve my form, and to strengthen various muscle groups to ensure I stay injury free. We're working hard together to change my gait and it's definitely having a positive impact. There's no way I could do this successfully by myself.

Medena's always positive and provides plenty of encouragement during our sessions. Would definitely recommend her to anyone in the area.

Coach Medena has been a great coach in teaching me drills and adjusting/tweaking my swimming technique for a triathlon. She is informative, patient, and encourages me, which is great! I have tried other swimming programs in the past couple of years, but none of it has helped me a great deal. However, after just two lessons with Medena, I have already progressed a lot and have easily doubled my swimming distance. I now feel confident that I can finally reach my goal in completing a triathlon. I would definitely recommend Medena to my swimming friends!

I love Medena and I'm so happy I found her! She took the time to call me up before we even met, so we could chat about my training and experience so far, my goals, injuries, etc.
We understand each other and communicate well, and she is both firm and encouraging as a coach. I always look forward to our sessions! She has given me endurance and strength building drills and exercises, daily core work and lots of tips and tricks on how to improve my stride and avoid injury. I am finding a strength in my core that I never experienced before, even in my 15 years as a professional dancer. She gave me valuable advice on taking care of an ankle injury that has been affecting my running for quite some time now, and showed me a supplemental workout to do while it heals, which made me feel MUCH better about the fact that I can't run right now! I will be back soon, injury free thanks to Medena, and I know I will be running for a very long time.

I’ve been running for fitness for a few years, and much like everyone on the planet I thought I knew how to run before going to coach Medena. But I was wrong! After just one session she was able to drastically alter my form to be a much more efficient and safe runner. I’ve always been concerned about whether running would hurt my knees as I get older, but with correct form I’m no longer worried.

Prior to taking lessons I was also getting a little bored of running, but now it’s fun. She was able to tailor my training to maximize the little time I have to run each week, and I continue to see big improvements in both speed and comfort. It’s also carried over into my other activities like mountain biking. My general level of fitness and strength has greatly gone up and for that I am very thankful to have found Medena!

Coach Medena was fantastic. After taking the time to thoroughly understand the specifics of my athletic goals, she brought all her years of experience to bear to help custom-tailor a training program best suited to help me reach those goals. She was incredibly patient, as well as creative, in thinking of ways to help me break through training plateaus. Highly recommend.

I am a beginning triathlete who needed some help with my swimming. I tried different things- DVD, group classes, etc. After 1 session with Medena, I took off about 1 minute from my 500 meter time. In the 2nd session I actually started to really enjoy swimming. I'm signed up for my 2nd triathlon actually wishing that the swim part was longer. She is very encouraging, and was able to pinpoint the main error in my swim technique immediately.

Coach Medena was awesome! Can't wait to see her again! She has the patience of a Saint.

I am training for my first triathlon, and Coach Medena helped me immensely with open water swimming. I have never done it before, and after two sessions, I went from fearing the open water to being quite comfortable. She gave me extremely valuable tips, from how to start the race, what to focus on while swimming, what to do when the unexpected happens, and transitioning. She noticed a few aspects of my stroke that could be modified, and gave me drills that specifically addressed them. She is a wonderful coach, very positive! I HIGHLY recommend her!

I have made significant progress after each of my first two sessions of open water swimming with Coach Medena. She provides good observations and instructions, and gives me good tasks to work on to develop my technique in between sessions.

Within forty-five seconds Medena identified issues in my pedal stroke and had me working on drills to improve efficiency. I felt faster after just one session! My only regret is that I didn't find her years ago.

Training with Medena was like finally reading the manual for my triathlete self. I had been competing in Sprint and Olympic races for a couple of seasons with moderate success, but was not progressing or reaching my most recent goals, frustration was setting in. Medena is helping me to achieve those goals by teaching me how to incorporate track workouts for speed and pacing, interval training on the bike, and brick workouts. She analyzed my run technique and pedal stroke mechanics to make me more powerful and efficient. She has a great attention to detail and is always observing and making suggestions on ways to improve. I have had several “Aha” moments where she taught me a better way to do something, she really knows her stuff. She is also very nice and fun so you feel like you are training with a friend.

Thank you Medena; I get so much out of the swim coaching. You are a great teacher. I wish I could could bring you to every swim I do. :)
Medena's coaching helped me make the transition from a relatively in shape weekend athlete to a competitive and fit triathlete. Now I am performing better than 25 years ago, having achieved my goal of completing several Half Ironman Triathlons including my P.R. of 5 hrs and 28 mins! Medena is passionate, knowledgeable, motivated and kind. Coach to athlete communication is outstanding. She took me to a higher level as an athlete, competitor and person.
