I'd like to try a road race at the local senior this coming March. I've never raced, but would like to see what its like with other guys in my age group. But, I'm not sure how to train for this. I'm comfortable riding in a group. I'm 67 - 5'10" - 190 lbs. The websites I looked up seem to be geared to 20 year old athletes but I'd like to do a good job in my first time out. Any help appreciated.
