20 min TT No.4

Today I did a 20 minute TT on the rollers. It was the first one I’d done since March

Heavy rain forced me onto the rollers today. Recently I’ve noticed that I can seemingly go faster with less effort. I wasn’t planning on doing the TT today. I was aiming to do ten minute intervals at increased speed and see where I got.

I did 10 minutes at 52 kmph, 55 kmph and then 58kmph. I was feeling really comfortable on the bike and thought I’d have a go at holding 62 kmph for 20 minutes.

I started out well but as the session progressed I kept losing the back end of the bike a bit. At this time of year I put lots of oil on the chain to compensate for loss of oil in wet riding conditions. This is not a good idea for the rollers though and the back 2 drums became increasingly slippery. I wasted a lot of time, effort and most importantly speed in trying to keep the bike stable. I was confident I could beat March’s effort though, so I kept going.

I averaged 61.5kmph (60.5 kmph in March) which is quite satisfying. The average heart rate was also lower at 160 HR (165 HR in March).

With the chain cleaned properly I’m confident I can average about 63 kmph next time, Looking forward to it!
