29 miles at 19.6. However for first time rode with my group in this setting before getting dropped. We drive to park and leave at 7AM.

We rode 8 miles then two laps around Homestead Race Track (6.2 miles per lap). Stayed with group on first lap at about 22 MPH. So far so good! On second lap goal is 25 or less, so kept up for half the lap at 23-25 MPH. At that time was averaging 21 for about 16 miles-fastest ever for me.

Then got dropped and limped home mostly alone when average reduced. Anxious to try again as they do these interval type rides twice a week and regular 21 or less MPH ride on Saturday.

FWIW I'm oldest rider, although very fast ones are in 55-64 age group.
