We were expecting cold rain but we lucked out and didn't have to run in the rain.
The first lap was pretty fast (2:02) and my calf was just getting loosened up. After lap 1, we stretched and that helped my calf a bit after that. It still wasn't perfect but wasn't bad enough to stop or complain.
I ran in lane 4 and Jen ran in lane 3. We ran 400, stretched, then repeated running 400 and walking 200.
After we were done we talked a long time in the parking lot in the cold and figured we should have just kept walking to get more miles in.
The workout was more of a struggle on the runs then the walks were easy. Maybe it was the calf, all the talking, the fact that I was in an outer lane, trying to handle looking at my watch in the dark, or all of the above that made it more of a struggle.
I always find how the Garmin shows a track to be funny. 1 lap always is way off. All the rest should be over top of each other and they aren't.
