I agree w/ alaric. But I rarely get to ride anywhere nice and last year I went to Big Sky for 5 days and wanted to get as much out of it as I could, The first 4 days were fine but halfway through the last day I could barely stand up. I had no real fatigue before that It just snuck up on me. My legs couldnt take it anymore so before I go anywhere next year I'll just do some wall squats the month leading up to it to make sure I get my full vacations worth.
