In the summer of 2013, Ryan Cooper took a few weeks off of work to answer a question: could you accurately predict a cyclist's performance using a fast, easy-to-use model? Over five years later, Ryan is the co-founder and chief scientist at Best Bike Split, a tool that helps cyclists of all levels develop optimal pacing and training strategies using proven technology. Dave Schell sat down with Ryan to talk about how Best Bike Split came to be, how athletes and coaches can get the most out of the software, and other optimal strategies to use before and during a race.
