I'm leading a GDB ride this Sunday afternoon, departing from the White Rock "TP Hill" (the parking lot on the hill across from the boat houses northwest of the 7-11) at 1PM.  We're heading out along the I-30 and Hwy 80 service roads out into Mesquite and back, for about 45 miles total.  One stop, at the turnaround.
 
This will be a fairly hilly ride, but I plan to keep a "constant tempo" pace, roughly 16mph on the flats and not killing ourselves on the climbs.  If you're a rider in good shape, please consider joining in!  Weather forecast is for sunny and almost 50 degrees, so it'll be brisk... but not wet!
