NealH and I rode the Assault on the Carolinas today. It was a beautiful day for a ride though we seemed to have a headwind much of the day. 65.7 miles in 4:14 ride time and over 5000' of climbing. Funny that the 3 Garmin 800s we checked had total elevation gains from 5600' to mine at 5060'. The ride organization claims 5600'. My 800 always reads low.
