If you haven't sponsored Eddie Izzard yet, now's the time!

Tomorrow is the last day of Eddie Izzard 27 marathons in 27 day challenge.

So far, he has completed 25 marathons in 26 days, after losing a day to a medical emergency.  So he decided he's going to make it up by running two marathons (84 km) tomorrow, even though he's never done a double marathon before.  And, because apparently that's not challenging enough, he then decided to up his last day's run to 90 km, in honour of South Africa's Comrades Marathon.

Eddie is scheduled to start his double marathon at 5 a.m. South African time (which is about 2 hours after I click Publish on this post), and to end 12 hour later. 

I ardently wish him all the good luck in the known universe, and sincerely hope that enough money is raised that everyone involved feels fully satisfied that this increasingly herculean undertaking was completely worthwhile.
