I can't do Bay to Breakers this year because of my injured feet, but I'm sure you can. Sign up now, it's for a good cause, it's only 7.5 miles, and really, it's the only reason to get up early on a Sunday.

Sunday, May 18, 8 am; Financial District at Howard & Spear Streets;
$27 per person before 4/15;
$32 per person 4/16-5/15;
$22 kids under 18 before 4/15;
$27 kids under 18 4/16-5/15.

I might pay the money for the registration just to get a t-shirt!
