Running (Treadmill) 1:00:00 [4] 7.03 mi (8:32 / mi)
Treadmill hill progression - ran at 8:30/mile and started flat and increased incline by 1% every quarter mile.
I think I had the opposite problem with a treadmill this time. I got up to 15% on each go...and whilst I'd like to think I'm getting fitter there's no way I've gotten that much better. I think maybe this was just a dud treadmill as I've used the treadmills there before and they've been fine.
Still at 15% it was a good, challenging workout (also when I realised I started incrementing by 2% etc so I got through 2 rounds)
