I have had this lower back pain ever since I started riding about 6 years ago. It is only now it has really started to interfere as my racing is starting get more serious. I have found it only occurs on harder rides, when im under pressure when riding in the hills or racing. However I have noticed when it starts I can cope with it but it eventually becomes a really strong throbbing pain and I need to stop. When on training rides I can stop and take a break and the pain goes away and usually doesn't come back. It is only recently when I have started doing bigger races (100km+) where you are constantly under pressure and unable to stop that it really effects my performance. Now im no old guy, im only 20. I have had a bike fit and feel great on the bike and I have been told that it can be to do with tensing the arms too much, but even if I try to relax whilst riding it doesn't go away. I thought it might be to do with weaker lower back muscles? (im your typical cyclist very little upper body strength
)I was hoping some of you guys might be able to shed some light on the area?
Cheers, OJ
