Have been putting in a few harder solo rides out on the road over the last couple of weeks and, like the title says, I’m getting a burning pain right at the bottom of my back when I get out of the saddle on climbs.
The pain then stays until I stop and straighten up / stretch for a couple of minutes.
This hasn’t been a problem on the trainer or doing easier, but longer, club rides.
Today I had the pain and stopped for a few minutes, then I was fine all the way home pushing quite hard on the flats, in the drops.
Before anyone mentions core strength, I don’t think it is. I’m doing quite a bit of strength training at the moment. I’m sort of wondering if it might be related - I’ve been doing quite heavy deadlifts recently. My back actually feels really good generally though, but I wondered if it might have tightened up.
I did have something similar (but different) a year or two back and this turned out to be tight glute medius. I suppose this could be related but I don’t see that stomping out of the saddle would bring this on.
I suppose it could just be a matter of getting used to riding harder outside again but any ideas on what might be causing this would be appreciated.
