Most of my rides are solo and after today, my confirmed preference. I was invited to go to a rally with some other guys (all but one ride regularly together). Ends up being a foggy morning so only 2 of the regulars, along with myself and another newbie to the group show. I knew there might issues when out of the gate (and from every stop there after) these guys throttled through the gears as fast as they could. Now my 'ol girl eventually gets up to speed, but tearing it up from a stop is not one of her strong suits. One of the guys behind me whips around me and weaves around another rider (all in the same lane). I don't like that. I like cruising the highway between 55-65 MPH, depending. As I reached 72 and these guys were still pulling away, I decided 70 was it and I could make the trip alone. A few miles into it they slowed and I caught up, but the whole trip was a game of them pulling away and slowing down (for me I figured). Before coming back I tell them I'm going to take it easy on the way home so if they want to go ahead without me, to do it. One mile out from the rally, they stop in the middle of the highway and almost cause a wreck (a lot of bike traffic). Turns out one of them had to use the bathroom, so they had to figure this out while stopped on the highway-UGH! The rest of the trip they stayed way ahead of me on the flats and I would catch up on the curves. There were other things I could add, but... It just wasn't the relaxing ride I had looked forward too. On the upside, there were a lot of neat bikes to slobber over and I made it back home safe. Do you guys prefer to ride in groups or solo?
