So we finished C25K on Friday… what next? C25K.2? I stumbled across another program that takes it up a notch. Active.com’s 5k to 10k program. It’s an app but thanks to a fellow redditor I have the program in text form. Keri and I started this new program yesterday afternoon. The main difference between the programs are longer runs, more speed work, and no walking intervals. Exactly what we need.
