Hi everyone. I thought I would ask this question here, since LD riding might produce this problem more than other forms of cycling.

I’m a 6 foot even 52 year old. I started fun riding and commuting a year ago. I was 240 lbs and I started by riding 50 to 100 miles a week using a Giant Cypress comfort bike. Everything went very well. I achieved steady weight loss to 220 lbs and also reduced more than 7 inches reduced from my waist and 7 inches from my belly during the first year.

Now I’m riding even more and I’ve upgraded to a Cyclocross bike set-up as a road bike.

Last month I logged 500 miles, I typically ride 30 to 40 miles every second or third days. I've always had some lower back pain, but the pain would not last more than 48 hours. Recently I've been able to stay on the drops about 60 to 70% of the ride and I've increased my cadence from 75 to 90 rpm. Speeds are up from 15 mph to 18 mph average, according to my computer.

Now I’m waking up every day to minor back pain.

I can’t decide if this is normal “no-pain-no-gain” or something that I need to resolve. In the case that bike fit is the issue, I’ll add the following info. I use a size 60 Soma Double Cross. This bike was professionally fitted by a good quality LBS.
