Another question. I have done a few rides of 27-34 miles with no problems. Other than a slightly sore backside. I am currently using mountain bike padded shorts and gym shirts (not cotton, think loose under armour or Nike type gym shirts). They seem comfortable. Is there any reason I should buy bike shorts and bike jerseys if these are working for these distances? It's a six day trip so I guess that would mean Shelling out $500 for clothes which I'm not thrilled about. The daily rides will be longer though but I've had no problems with chafing or anything else.
