My rule of thumb is not to ride more in a day than you normally ride in a week. All of the above advice seems sound.

Yesterday I rode the PA Dutch Farm to Fork Fondo century (113 miles) in Lancaster PA
Ride Details & Prices ? Farm to Fork Fondo
I did it on my fixed gear bike with 70" gears. the ride had 6700' of climbing with a couple of 10% grades. It was a challenge, but I did not have to walk or change gears once. the ride was great. The roads were worn by countless buggies and very smooth. Each rest area offered a selection of local food. Some of the choices were:

- Homemade bacon
- Egg salad with local eggs
- Homemade pulled pork
- Local Peaches
- Local nectarines
- Local ice cream
- Local peaches
- Homemade sausages with peppers
- Homemade cheese with garlic
- Berries from the farm across the street
- Frittatas
- Turkey Hill Haymakers
- “Maple” drink
- Fancy raisin bread

Ride Safe,

Joe
