    Sore tailbone and looking to avoid it again.

    I'm still trying to get back to riding, 56 yo and 400 lbs. I'm looking for idea's from riders that have gone through the same problems. I fall back to my recumbent trike from time to time when I'm sore, but rather ride my mountain bike. I do how the handlebars raised a few inches to sit more upright and been trying different saddles. I just got my first bibs and like them after one ride, installed a Specialized Expedition Gel saddle that is the best I found so far. But run into a problem yesterday, I rode 7 miles all road and hard surface paths and the new bibs and seat felt the best yet. I was riding with the daughter and wife so we were stopping every mile or so and on one of the short hops my rear was killing me, my tailbone felt like someone put there foot to it. I think I may have sit on the saddle a little too forward and sit more on my tailbone... Has anyone of you ever did this? I sit on a bench for a few minutes and felt like I needed to call it a day so I told the wife I was heading back and she could finish without me, I knew she would be fine with the girl since we were in a park. She agreed and when I got back on to head back I was not having the pain as the last stop so I finished the 3 miles of riding with them.

    We were going to go again today but I'm too sore and even have trouble walking today, I've even been looking into more saddle choices and even looking at something like a noseless saddle like a spiderflex or Spongy Wonder.

    But my main concern is the tailbone pain.

    It isn't just a larger person problem. I have had that same thing happen from extended times away from riding(like 3 wks or so) and I've been competitive for 15 years. It has to do with the tendons/muscles that go from the back of the legs to the low back. Stretching and moving are the best things I've had. Ease into the workout and ease out of it. Sometimes tilting the seat rearward a hair can help too.

    I've had tailbone pain for 20 years. I've broken it several times and I have a very hard time getting comfortable for any length of time. Always shifting around. I just started biking this year and I've struggled with it. You have to sit on your "sit bones" which means siting further back on the seat. Google a picture of it and you'll see what I mean. If you sit too far forward on the seat it pushes on the soft tissue under the tail bone pushing it upwards and gets very uncomfortable. I never imagined I would have to learn how to sit on a bicycle seat (properly) but I did. It's not as bad now but it's still an issue I'm going to always have to deal with (biking or not). I did a 35 mile ride this morning on my hybrid and it was OK. I stopped a couple times for a few minutes and stretched, which seems to help.

    My guess is you're sinking into that seat too much. Those thick padded seats seem like they should be better, but they usually aren't. You really need a firm, thinly covered seat that you don't sink down into. Seems counterintuitive for us big boys, but it's true. Sit on the assometer and get a firm seat the right size for you. If you got your saddle from a Specialized bike shop, they should exchange the saddle for you. I ride a Specialized Avatar, but that might not be the seat for you either.

    I'm thinking the key piece of info in the OP is "I was riding with the daughter and wife so we were stopping every mile or so and on one of the short hops my rear was killing me..."

    I've run into the same issue. It's not a cinch for big, out of shape people to get on and off the bike seat over and over. Particularly when I was starting back riding and had a kid on a 20" single speed wanting to stop a lot, I'd occasionally not get on the seat correctly and essentially the front horn would meet my tail like a boot tip in the rear. Some practice with mounting smoothly may help, and as you get fitter it may be easier to land smoothly and correctly every time.
