What Athletes Are Saying
Sandro’s expertise and attention to detail has helped me improve more than I had thought possible. Through his online coaching, I broke my 20 year 5K PR by 21 sec to 15:48. And with his plan, I was able to break my HM PR by almost 4 min to 1:14:29.

Sandro’s very well thought out coaching has assisted my running greatly, being able to fit my runs around the changing hours I work with my job. I am certain I would not have managed a 2:58 marathon PB at 45 years old without Sandro’s coaching.

Following the competitive marathon plan helped me reach a new PR with a first place overall finish in 2:39:37 on a hilly course. Sandro’s scientific approach ensures that every run and workout has a purpose, arriving at the starting line fit, healthy, and fresh.
