COROS Coaching Corner

For many reasons, not all athletes want to hire a coach. While a coach may not be available to them privately, that doesn’t mean questions may not arise that need answering. Questions such as: What should my fatigue be at prior to race day? If I was sick last week, what should I do this week? Why is my threshold getting slower as I run longer?

There are many questions you may have on your journey to the LA Marathon. Let our three qualified coaches answer your questions and help guide you on your path to success!
