‘I Maxed Out My One-mile Pace in 28 Days’

By Luke Chamberlain, gear and tech editor at Men’s Health

As a runner, I’m a creature of habit. Every week, I run the same routes, the same distance and at more or less the same pace. As a result, personal bests have become a thing of the past. Trainer Jake Berney’s programme was my opportunity to inject some variety back into my training – and, with any luck, get back to setting PBs.

Ahead of the challenge, I checked my Garmin stats to find out my fastest 1-mile. The time to beat? A respectable six minutes and 36 seconds.

The first interval session was more challenging than I had anticipated. Running at 95% effort – or as Berney puts it, ‘with minimal ability to talk’ – isn’t something I was accustomed to. My legs rarely move that quick and I found sustaining near max pace, even over 200m efforts, tough by the eighth interval.

But by week four, my body (and mindset) adapted. The intensity and volume had increased, but once I knew how to settle into a pace and rhythm, I could feel how the interval runs were benefiting my speed.

By week four’s tempo session – a sustained 80% effort – I was running out of breath less and found it easier to hold my pace throughout. As for the easy and long runs, they became a welcomed rest in between the speed sessions, giving my legs a chance to recover.

So, did I max out my one mile? After week four, I laced up my fastest shoes – the Hoka Mach X 2, if you’re wondering – found a quiet stretch of the Thames and clocked an improved one-mile time of six minutes, eight seconds. It hurt, but it was the shake-up I needed.
