I am a terrible swimmer, too. I can swim, and I am not afraid of the water, but I really don't like being in water where i can't touch the bottom or get to the edge of a pool. I've realized that there's some issue with my left shoulder mobility, as I can't really do the front stroke correctly on that side. Also, during the few times I've used swimming as a sub activity when i was injured, I had the problem of swimming with my contacts. I have yet to find a pair of goggles that work for me, as I have a child sized head. When I finally found some that kept the water out, they were too tight. So, I usually end up doing a breast stroke or side stroke, if I swim at all. Putting my face in the water makes me feel claustrophobic, which is a new development!
On that note, I did go out on the trail this morning at about 7:30. I wasn't wearing bug repellent, although I was mostly covered up. I felt really good and managed to run (slowly) about 1.5-2 miles, up the ridge. I did not do the whole trail, which is door to door, about 4 miles, because it was getting hot and I didn't want to take off my sweatshirt. The last time I was on the trail was April 16th and I am in way better shape now, based on my ability to run up the very steep climb (15%?) to the street. I guess that's what cycling up big hills does for you.
