3 so far this year and hopefully another 5 more before the end of the year.
I did one a month or so ago with my club and that was the first one that I didn't either get rained (and lightning) out of or crashed out of.
I've now done one each of the last two Saturdays and plan to do one each Saturday for the rest of the year. I ride 23.5 miles to our Saturday ride, ride 55-65 miles with the group, and ride another 23.5 miles home.
