whats the most distance you've travelled

[BUSGO]

I can quite comfortabley do about 800 in a day if I want to. Especially once daylight savings kicks in. If I have a long day in the saddle, I leave at about 6am and pull up at about 4pm.
If you had a good 1 hour rest in the late afternoon, you could easily do another 3 or 4 hundred ks before dark.

I don't know if you will get an answer from Cowboy or Tone but they have bums that are shaped to the saddle and have been known to do much longer day rides.
