Have a go at that and get back to us.
OK I rode last night and it was a tough ride. I rode about 25 minutes to the base of a 8% grade that took me about 10 min to climb. I normally shift down to keep the cadence up, but this time I didn't. I just mashed and mashed it out. After about 1:45 my HR reached 160 so I had to slow down a little down. I usually try and keep it around 150 as my Z5 is around 165. I honestly thought I could push out at least 2 minutes, but I was huffing and puffing after just a minute and couldn't keep my HR down without slowing to a pace under 5mph.
So much for Bing Ring training. I'll have to add in more HIIT training on the trainer as clearly my fitness is not where it needs to be.
