"Having done three IRONMAN 70.3 races, I knew I wanted to take the leap and do a full IRONMAN.  After speaking with about 5 different coaches in the San Diego area, I knew that S2F Endurance Coaching was right for me.  His approach and philosophy towards the sport, brought a fresh perspective to your everyday triathlete.  Chuck is very personal and easy to talk to, but also has the experience to back up his training plans and knowledge of the triathlon world.  He was able to put together a plan for me that took into account other life responsibilities I had going on, and worked with me on tailoring my training around everyday life, and my goals I had set out.  He was always very easy to get a hold of, and always willing to go above and beyond to make me feel like I was not just another person he was coaching. Everything was detailed and laid out for me to do my training session in the most efficient and effective way.  After training and being coached by Chuck for the last 6 months, I successfully completed IRONMAN Texas in April"

"I met Coach Olson this summer and have benefited from his in-depth knowledge on nutrition and hydration ever since.  When we met, I had just started training for my second Ironman distance.  My process was to consume when I felt the need and, never connected my lack of a plan with losing energy and effort during both long training sessions and races.  He has completely turned this around with concise plans and now, instead of struggling to finish I finish with energy.  I am also happy to report that, since working with Coach Olson, I have finished top 5 in both 70.3 and Olympic distance races.  Thank you Coach.  You have made a huge difference in my racing life.

"I contacted Chuck after deciding that I was ready to start training for triathlon races (with the ultimate goal of completing an Ironman). After hearing back from him almost immediately (and with great enthusiasm), there were two hurdles for me when deciding to make a commitment. One was that I am a complete novice in endurance sports; the second was that I am a graduate student in Florida and Chuck coaches in California! I decided to begin training with Chuck because of his long history of racing successes and coaching novice endurance athletes. I’ve stayed with Chuck because he has been an amazing remote coach! He provides workouts two weeks in advance and is constantly watching my progress and giving me feedback. We talk on the phone often and he recently coached me through completing my very first triathlon (ever!) which was a HUGE success."
