R.I.P.The man who might have been the greatest ultra-endurance athlete in history, Jure Robič, died in a car accident at age 50.
How great was he? He holds the 24-hour cycling record: 834.77 km (518.70 miles). Yes, that's over 21 miles an hour for a 24-hour period.
If you missed it originally, here's a NY Times article about him titled (appropriately) That Which Does Not Kill Me Makes Me Stranger. The "stranger" part was in reference to some of the absolutely bizarre things that ultra-endurance athletes must pass through during their events. There's also a documentary (which I haven't seen, but will soon): Bicycle Dreams.
