From 3:59 Marathon To 2:34, with Danny Huibregtse | Extramilest Show #49

By December 14, 2021May 20th, 2023No Comments
Danny Huibregtse running fast in the streets of Rotterdam for the marathon.

Danny Huibregtse (Strava) from The Netherlands, improved his marathon times from a 3:59 to a 2:34, using heart rate training. In his last marathon he ran a 34 minute PB from 3:08 down to 2:34, an incredible performance!

We discuss his approach to training and racing, how he improved so much and recommendations for other athletes looking to race faster. 

Danny and I first connected during the summer of 2019. Danny has been a part of our Personal Best Training Program and it has been really exciting to follow his training and racing progress over time. 

Our Personal Best Program is a running coaching program and we often focus on MAF low heart rate training and race day strategies. To learn more, check out PBprogram.com

I hope you enjoy my conversation with Danny Huibregtse.
