Yesterday, I was scheduled to do an 8-mile training run on single-track trail. I also had a boatload of work to do. But the night before, I’d done the math: 8 miles on trail, that’s about 1 hour and 20 minutes at my current pace. Add in 20 minutes of travel time to and from the trailhead and I was looking at an hour and 40 minutes (OK, an hour 50 when you throw in stretching and the fact it probably takes longer than 10 minutes to get to Umstead). I factored that into my workload, got up an hour early and got to work. I can make this happen, I thought.
