Cycling and a sore bum

I quite often get a sore arse when I’m out on a long ride on my bike. Up until about 30 minutes ago, I’d put this down to merely needing to build up some resistance by doing longer rides, and that seemed to be working, as my last 2 long rides (40+ miles) did not make my butt feel sore. However, I went out for a 57 miler today, and my arse was sore by around mile 33. The last 15 miles coming home became progressively more uncomfortable, to the point where I needed to stop a couple of times to try to alleviate the pain. As soon as I stopped and got off the bike, my arse was totally fine, but as soon as I got back on again, the pain returned.

The types of butt pain you can get from cycling can vary. The type I get is not from chafing, which seems to be a common problem. Instead, I’d describe mine as more a pain near a boney area, but hadn’t figured out what it was.

I did a bit of googling this evening to see what it could be. First, I needed to figure out what part of my skeleton it was that was sore. That was quite easy – it’s the ischial tuberosity, aka the “sit bones”. From there, I discovered an excellent article on the Cervélo site about the four and a half rules of road saddles, where rule #1 hit the nail on the head.

Ultimately, I’m now fairly confident that I have been sitting too far forward on my seat. So, in other words, my sit bones have not been resting correctly on the seat, and have been therefore resting down the sides of the front (narrow) bit of my seat. Even thinking about it makes it feel sore. Instead, I need to sit further back – probably all of an inch further back, and when I tried that on my bike while stationary, it does feel significantly more comfortable.

I’m not sure what the pedalling action is going to feel like, mind you. However, this is on the bike which I’ve had fitted professionally, so therefore I should really give it a go and see what happens. I’ll be out on the bike doing various errands tomorrow anyway, so that’ll be a good time to see if it is indeed the answer!
