Get updates, and a chance to win cool prizes, by following Edward Norton on Twitter. We’ve raised more than half a million U.S. dollars so far, but it’s not too late to donate. Click here to sponsor one of our runners. PUMA is also offering a Maasai Marathon commemorative t-shirt in two cool designs, and half the proceeds go to MWCT. Also check out these Garmin maps of Edward’s training. Best of luck to all the runners!
