I was talking to a friend recently about funny workouts we've done. You know, the kind you do once and never again.
We did this workout once that backfired a little. It was WAY harder than I thought it would be. It was about 10F out and windy. We went to an area of high sand dunes. The wind had cleared the snow off a strip of the dunes all the way up. So we ran up the dunes with a sled in hand and jumped on the sled to go down. What I didn't realize was how hard it would be to catch your breath on the sled and just how quickly it took to get to the bottom. None of us thought to rest between intervals because we had it stuck in our mind that we brought the sleds to reduce the rest. A lot of us were gong down face first on our chests which didn't help the breathing situation. I think we made it about 20 minutes, maybe not even that long
The other one was a workout I did with a friend. We were training for a mountain race and decided to run up a 1,200 vertical climb mountain five times to simulate the race we were training for. It was 20 something minutes up and 20 something minutes down. B/c of the down hills we were not used to neither one of us idiots could walk for the next three days after the three hours and twenty minutes of hill repeats.
