Hmm well this was interesting… On the one hand it was pretty idyllic… very easy running through rye nature reserve in the sun, after a sy at work… The only thing was, I had to slow myself down to a point that felt odd at times, in order to keep my HR below 135. I definitely could run that pace forever- I barely even sweated!- but if that was on total flat I’m not sure how I’ll be able to run in the country park at all without going over 135… and if I have to walk every slight slope won’t I lose a lot of fitness?
It raises a few questions and I’m glad you asked them. You are right, yes if suddenly every 60 min run we started doing like this, rather than previously where you had been running up hills and working hard, inevitably that would be a step backwards. But then it raises the questions, why have you picked up lots of injuries down the years? Perhaps that is because you have done those “easy runs” too hard all the time? HR training is one way of approaching your running. You don’t have to do it that way. If we do adopt that approach then getting a chest or arm strap is crucial as your data may even have been wrong here and you should find you can run quicker at Zone 2. Your dashboard says 6:12-6:33 per km for example. When I got a chest strap I could run faster that using my watch, so shows the data was inaccurate. As you discovered the benefit of this approach is you can do more, but, and it’s a big but, if you don’t have time to do more, it’s therefore not beneficial. From my experience at first when I did it, I was having to run slowly 6:00+ per km. But now, especially with the chest strap, I’m can hit speeds of around 5:15 per km at points and still be in Zone 2. So it’s quickly improved. But yes, going up hills does quickly spike my HR and I need to slow down. But if I was going to take on a 100K ultra, hopefully one day I will, I think I would walk pretty much every single hill anyway, that would be my strategy to get to the end. And what I did and will do again, at the Amble this year. Have a think, decide which way you want to go, we can always experiment for a bit more. In terms of HR straps I’ve got a coospa which only cost ยฃ20 so they are cheap.
