Ride was great. Met up with Sharon Haney's group at the AMC HV. From there, we rode up to Lake Dallas to meet with Mark Solow's group. From there, we rode up to the Smiling Moose Deli in Denton (Hickory St.). Ride was about 22.5 miles for me from home, and about 15-17 in, I started feeling a hump in my ride. I thought it was a spoke, but Kathy pointed out that it looked pretty wonky. I checked it out, and the bead was separating from the tire. Maybe sand got in there. Not sure. Either way, I needed a new tire. Charlie Haney was pulling SAG support, and he gave me a lift over to Bullseye Bike Shop. Picked up a Vittoria Randonneur for MSRP, about 30% over Amazon price which is good for an LBS. Plus, they let me use tire levers and a floor pump. Then, back to the moose because I left my helmet. Oops! By that time, the fast group was already pretty far down the trail, so Charlie took me back down to the the Lake Dallas meet where he was picking up another bike. I rode out to Corinth St to meet the group and test the tire, and then finished the ride back. I lost about 7 miles off of what I was hoping, but it was still a great ride. My average moving speed was 15mph, and average overall was 14.3 I'm really proud of that, and excited by how much group dynamics push me to ride faster. I'm modelling much of my push and coast on Sharon, who's a couple of levels beyond me in ability, but everyone out there has something I can learn from.
