About

I'm Greg Howes, a British runner living in Japan.

I've been running competitively for more than 30 years and have maintained a sub-3 marathon standard from my early 20s to my current 48-years. My interests include marathon training, masters running, trail running, strength training and helping busy runners continue improving as they age.

I write my training content under the pen name G. I. Holmes, and post running content on my Instragram account runner_Greggu
