How to Qualify for the Boston Marathon at any age, with Jeffrey Silver

Jeffrey Silver running Chicago Marathon 2019

Jeffrey Silver (Strava | IG ) is a 54 year old runner from Toronto, Canada.  For several years he has had the goal of qualifying for the Boston Marathon. He ran his first marathon in 2013 in 4 hours and 12 minutes. Over the years he improved, but he also experienced several serious medical challenges that set him back in his training and racing. 

He started implementing low heart rate training and increased his training volume, which helped improve his running. We take a deep dive into his training and racing and how he was able to qualify for the Boston Marathon two times in the past 6 weeks, I just saw him in Chicago last weekend running another PB. 

Jeffrey is part of my Marathon PR Training Program. This is an online training program for athletes who are ready to take their training and racing to the next level. It is a great group of runners from all levels looking to improve, from first time marathoners to those wanting to qualify for the Boston marathon, run Sub 4, Sub 3, etc. More info can be found at extramilest.com/marathon
