I went out on my longest ride in about 6 months, 38 miles in the saddle. I just came off two weeks of non-stop TR SSB1 sessions and cross training; I should have known better but I decided to add an 18-20mph group ride to that. I couldn’t handle it and I got dropped about 15 miles in, put-putted home by myself after that.
What’s worse is that I developed some lower back pain about 1/2 of the way home. The pain also involves some sort of muscle on the right side of my groin, it feels like it’s overly tight.
How much would a light backpack (5-7lbs) factor in to that back pain? I use the backpack to store patch kits, CO2 canisters, multitools, spare tubes, extra food, and a good-sized pump. During the week I commute with the backpack and my laptop adds another 5 lbs.
I read that backpain on the bike is largely attributed to poor lower abdominal muscle activation, but I’m wondering if the backpack is a larger issue for me. Thanks in advance for any help.
