How far?

I just read that the 24-Hour record was broken yesterday by Michael Secrest (no word on the relation).  Secrest rode 532.74 miles in 24 hours.  Get out your abacus as this is 22MPH!  What is really amazing is his 1990 record where he rode 1217 miles in 24 hours….while drafting a semi.

Can you imagine riding for 24 hours?  No less at that pace?
