James Patterson 10k/13.1 run test question

James Patterson

I was considering doing a 1/2 marathon in Chicago in a few weeks, but it looks like it will be colder than I'd like. Can I just do the 10k option on the treadmill? I've been doing my running consistently on the treadmill at 1.5%. Any thoughts/guidance?

James, we'd always prefer outside...maybe you wait and see? If it's really going to be bad, then Tmill it is...either way, that test is looming!
