I took my students on a service trip for spring break. It was a construction trip in which we did a lot of digging (digging dirt out a crawl space to get to the floor joists), carrying (buckets of dirt and a lot of lumber to replace said floor joists), and general construction type things. Going in, I knew I was in good cardio/endurance shape, but I never realized I have pretty decent functional strength to go with it. I mostly worked circles around my much (ahem) younger students and really wasn't sore after any of the work (maybe I didn't work hard enough!)
Back to running this week. The doc gave me the go ahead as long as I didn't re-injure myself last week. Overall, my back and hip feel pretty good (I took almost two weeks off pre-trip). So I'll give it a couple shorter, easy runs this week to test the waters.
