Dear Dumb Runner,
I have completed two marathons employing the run/walk method. I base my split on time, not distance—i.e., run 30 minutes, walk 2 minutes. Should I make it a goal to run the whole way? Or is "run/walk" just as valid?—Kevin, Chicago
Some people may scoff at your run/walk method, suggesting that you didn't really "run" a marathon, you don't take racing seriously, and so on.
Those people are assholes.
Congratulations on your marathons!
