About 3 weeks ago I bought a new Trek 8.4 and started riding for the first time since college (about 13 years) In the first 3 weeks I put close to 100 miles on, mostly doing short 6-8 miles trips daily. This past weekend I decided to up it and did a 15 mile ride on saturday and a 10 mile ride on sunday. Well now 5 days later my azz is still sore and I have not been on the bike since.
I had already changed out the seat to one slightly more comfortable than the stock seat; and I just ordered a pair of bike shorts (did not have them for last weekend) Is there anything I should be changing on the setup or doing differently on longer rides to prevent the soreness, or is this just something that comes with starting to ride again?
Here is a pic of the current seat setup.
