Have to admit that 4,000 ft of climbing in Florida sounds excessive to me. But 8 x up 500ft is enough. Bit like our hills round here but they are 10 to 15%. 6 of those and I definitely need PIE. Then I do 400ft climbing on the flat bit back home.

Wonder what Flatlands are like to ride?

Sounds like a good ride for this end of the season. Distance about right and just enough climbing to say it is interesting. But Rick has got it right-"It should be the Wonderful Hundred"
