Training goals

I'm trying to gradually transform myself into some kind of recreational athlete. Although I've done a few triathlons, a two-mile ocean swim, and just finished my first marathon this month, I still don't feel like I'm successful at these things. So I'm setting out a few goals for myself:

1. Pier-to-pier swim, August 1. I started training way too late this year, so I'm not going to set any time goal or anything like that. I'll just try to survive it.

2. 7:00 mile. I'm doing intervals right now for this target. I'm not there yet, but I think this is possible in the next couple of months.

3. Las Vegas marathon, December 5. My current goal time is 4:22, the same as it was in San Diego. In SD I blew out after 18 miles, and came in at 4:54. Las Vegas is flatter and it should be cooler, too. To be honest, 4:22 should be pretty easy.

4. 10k in 50:00. The Runner's World pace calculator says that if I can do a 7:00 mile, I should be able to do a 48:32. The best I've ever run was a 54-something, but that was in marathon training and I should be able to improve on that with my interval training.
