What Athletes Are Saying

Sandro, I ran the Mesa Marathon today in 2:49:27 h. Snuck under 2:50! Many thanks for your training plan. I felt very prepared going into the race today. 

Luke Malliard

I followed one of Sandro’s 16-week half-marathon training programs and really enjoyed the structure of the plan. I felt strong throughout the race and was ecstatic to improve my PR by 7 minutes and achieve my goal of sub-90 minutes.

John Lee

Hi Sandro, I had my HM race yesterday and finished in 1:31:55! Very excited about the result thanks to your plan.

NSCA-Certified Strength & Conditioning Specialist

Hi, I’m Sandro — coach and founder of RunningFront. I have been racing everything from the 400m to the marathon since my teens. I know what it takes to handle hard track sessions and demanding long runs.

As an NSCA Certified Strength and Conditioning Specialist with 12 years of coaching experience, I developed the 4-day running week for runners who don’t have time to run 5+ days a week but still want real progress.

My focus is simple: turn 4 purposeful runs into race day performance with effective, time-efficient training and no junk miles.

You’re not training alone. I’m available via email if you have questions during your training plan.
