Your guess is as good as mine! Submit your guess of how many miles we will—collectively—trek by July 29, day one of the Transplant Games. Spoiler alert: it’s going to be a BIG number. We’re not just talking about the 3,981 miles from our starting point to San Diego, but how many miles all 338 trekkers have posted by then. You can see the total current mileage on the My Virtual Mission website. 

Enter your best guess (or guesses) by 11:59pm PST July 28, and the trekker who guesses closest to our actual mileage will win a fancy pair of custom Transplant Trekkers shoes!
