Calvin Sambrook (56) and Josh Sambrook (23) share their journey of massive improvements in the marathon. Calvin ran his first marathon and had to get rescued at mile 23 (37km). Over the years with coaching of his son Josh, and self experimentation, he was able to improve to a 3:14 marathon time.
Both Calvin and Josh share great insights about Calvin’s improvements and also recommendations for other athletes looking to improve their running.
