Aquathlon Part II

I stopped at the water station on my way out of the transition area and then I took off down the trail. Immediately it felt pretty rough. My legs felt heavy and my calves were tight. My breathing was ragged, not the way it should be when setting out on a run. The trail was level for a while. I just jogged along hoping I could settle into a rhythm. The trail brought me out onto the road. I followed the road for a few hundred yards and then made a sharp turn onto another trail. They had a guy stationed there to make sure no one missed the turn.
The new trail was steep and narrow. My calves were cramping up. After a minute or two I slowed down and walked. I was thinking I might have to walk the rest of the way. Somewhere around there a guy overtook me. I stayed behind him for a minute because there was a part of the trail that was so steep he had to walk it too. But then the trail leveled out a bit and he was out of sight quickly.
After another minute I started trying to run on the easy parts of the trail. There were a lot of spots that were steep enough I had to walk up. Then I started finding some spots that were steep enough I had to walk down. I noticed the drawstring on my suit was uncomfortably tight, so I pulled it loose.
Run a little, then step carefully then run a little more. I found I convenient mens room (large tree) just off the trail and when I emerged from behind it a few moments later I actually felt much better.
I continued for a while stepping carefully through the tricky spots and running between them. Then the trail I was on junctioned into a wider trail. I wasn't sure of the distances at that point but I think this was somewhere around halfway. I realized that my calves had finally loosened up. The up and down part of the trail was mostly over. The remainder looped around part of the lake and then over a bridge and back to the beach. I was feeling pretty good by this time. Every time the trail changed direction or crossed another trail I had to pause to check the markers.
A little past where I think the 2 mile mark was I overtook another racer. I told him I was coming up on his left and he waved a hand to acknowledge. I glanced at his number and realized he wasn't doing the aquathlon he was finishing out the 15k trail run. Meaning he'd been out on the trail since around the time I started my first swim. "looking good" I shouted back to him. A short time later I crossed that bridge and from there it was just a short distance past some picnic grounds and the playground. By the time I spotted the finish line I barely had time to try to sprint to the end. Just under an hour and 10 minutes and the toughest 5k I've ever run.
