I went into this 4 mile race not really knowing that much about it. Like, for instance, I thought that this was a road race. It was actually a race through a wooded park. So most of the race was on paved trail wide enough for 3 or 4 runners. Some bits were not paved at all. At one point in the first mile, I overheard someone say, I didn't know that this was a single-file race. I had to chuckle because it was true. It was a bit difficult in the first mile as runners sorted out where they belonged with regards to pace. Supposedly, we were to line up by pace, but it was difficult to hear what was going on, so I, like most people just walked up to the starting area without regards to pace at all. But it was a pleasant, if cold, run through the woods in San Antonio. I ran the whole way except for at the two water stations. I'm not a fast runner and my goal is always to finish the race, but I'm happy with my time as well (43:38).
