I’m currently having a break from structured on-bike training while I do a running training plan (4-5 Days a week) as a precursor to trying Triathlon (running being my weakest sport). Since starting this plan there’s been the expected drop off on my cycling fitness while I focus elsewhere, but I’m really really struggling with climbing.
For example on a local climb that usually takes me 23-25 minutes took 31 minutes last week (over 20% slower). The thing is my HR didn’t go over 150 and my breathing wasn’t too bad, I just had no power in my legs. Fuelling had been normal and I didn’t feel like I’d bonked, I just felt weak. It’s not just long climbs either, got dropped by my social group last week on a 5 min short sharp climb but at the top I wasn’t remotely out of breath and had an HR of around 145. Both times I just couldn’t get any more out of my legs.
I considered the possibility it was muscle fatigue from all the running, so had a 6 day break from any sports and found I was essentially no faster yesterday than the previous week.
Also, steady/flat stuff seems to be unaffected; I can still go pretty deep on the flat, get my HR up and get the odd PB on a flat segment. Explosive power is OK too (sprinting and even up small hills if I have some momentum) but sadly I don’t have a PM so it’s a bit harder to quantify everything (I backed IQ2 a couple of years ago and am stubbornly holding on despite everything).
Just wondering if anyone has any ideas, or if anyone has had the same experience when taking up running (Google suggests cross training should be beneficial if anything), because it doesn’t feel like it’s as simple as de-training, although I could be wrong so I am asking the experts!
