About 5 years ago I got a Trek road bike. It's done 3 RAGBRAIs with me and all the training between. Last year I started getting some major irritation down there. Butter helped some, monistat was better. This year it's worse. What's going on? any wisdom out there? I'd rather not invest several hundred dollars in different saddles until I just land on one. Is it the shorts? Any recommendations?
