24 hours until Vineman

The Vineman half-ironman (1.2 mile swim, 56 mile bike and 13.1 mile run) is tomorrow and it should be interesting, to say the least. I use the term "interesting" in the literal sense in that I have no idea what is going to happen, even though I've done this race twice before. I'll break down the unknowns for you:

START TIME: In years past I've been in one of the last waves, starting at around 8:30. This is usually detrimental because the afternoon temperature climbs to around 95-100, so earlier starting waves get an advantage of not having to bike and run in as much heat. This year my wave starts at 6:46am, which means I avoid a lot of the heat and theoretically should have a faster time.

SWIM: I think I am faster then last year, but lack the base to complete the 1.2 mile swim as easily as I have in years past. I just need to remember to keep good form and finish strong. In prior years my times were around 44 and 39 minutes. Projected time this year = 39-41 minutes.

T1: Earlier swim wave means I have to run 10 yards out of the swim to my bike, not 100. 90 less yards to run in bare feet on gravel slightly covered with astro-turf should make T1 quicker. I usually don't care about T1 times and take about 5 minutes, but since I have this early wave start maybe I'll shoot for 3:30 or so.

Bike: Ugh. I've been training with Team in Training for Pac Grove (olympic distance) and haven't gotten in enough long rides. I think my longest ride in the last year has been 35 miles. Hopefully I can stay focused enough to notice my legs breaking down. If I can break 3:40 on the bike I'll be happy.

T2: nothing to say

Run: Ugh. I've had a heel injury for the last 5 months or so, and about a month ago I quit running entirely to try to get it to heal. It didn't. I've been running in the pool for the past couple weeks (I think for an hour, 5 times total). So how will I do on the run? Unknowns:
--Will I be stopped by the heal injury? Or did my month off from running allow it to heal enough so that I can finish this thing?
---Is pool running so incredibly beneficial that I'll be able to run the whole 13.1 miles? OR is it only marginally beneficial and I only have a 2-3 mile running base at this point?

So in the spirit of keeping focused on goals, here's what I hope to accomplish...each goal is superseded by the previous one:
1) Don't injure myself
2) have fun, plus goal #1
3) finish the race, plus #1 and #2
4) Accomplish 1-3, and finish in under 8 hours
5) Accomplish 1-3, and finish in under 7:50 (personal record for course)
6) Accomplish 1-3, and finish in under 7:35 (personal record for a half-ironman)

Goals 1-2 should be easily attainable, 3-6 might be a tad harder
