I've been hiking hills while carrying MC a lot lately, in part to train for the late hills of the north face 50 mile, where everything tends to feels tired. Carrying 25 lbs of toddler on a 20% grade feels about the same as the last couple hills in a 50 miler. In doing so, we came up with an interesting idea: I'd carry her through a 5k, and PL, who only runs a few times a year, would try to beat us.
It was cold, but the turkey was out. And it was a close contest--we were beat by about a 100 foot lead. Maybe next year MC will do the kid's run.
