I also love the Accelerade
2Young: I've looked at the kid's tri link many times. Logistically we just haven't found one that fits our schedule yet. It's hard to do with t-ball, soccer and dance classes. Both of my girls have done a couple small tri's, and the oldest one certainly would benefit from them right now.
BnB: from Runner's World your
times for different distances using 23:48 per 5k should be:
1500m 6:38
the mile 7:09
3000m(3k) 13:50
3200m(about 2 miles) 14:49
5000m(5k) 23:47
8000m(8k) 39:08
5 miles 39:22
10,000m(10k) 49:34
ten miles 1:22:05
a half marathon 1:49:17
a marathon 3:47:51
I've been told that speed work should be done slightly faster than 5k pace or 20-25 seconds faster than mile pace. Thus your speed work should be done between 7:30-7:35 mile pace. You'd likely benefit more from shorter intervals than longer, as the races you've been competing at have been shorter. I'd recommend doing Yasso 800's; starting at 4 or 5, then increasing the number as your endurance for them improves. A sample Yasso workout would be:
1 mile warm-up
.5 miles at pace (7:30-735)
.25 mile slow (approx. 1 minute more than marathon pace = approx. 9:40 pace)
.5 miles at pace
.25 slow
.5 miles at pace
.25 slow
.5 miles a pace
1 mile cool-down
Yasso's are generally a really good predictor of marathon finish time as well. Once you get up to 10 intervals, whatever average time you have per 800; should reflect marathon finish time. Thus, if you can do all 10 in 3:45; you should be able to run a 3:45:00 marathon.
I also love the idea of switching cadence and power during TT's. I'll need to work on this. On my road bike my average cadence is generally really close to 90; while on my tri bike, it's closer to 85. I have done workouts at 100, but do not like doing them.

My update:
I royally detest this time of the year
This morning at 5:50 it was 74 degrees in 91% humidity
I took my lumps on this mornings run, and want out really slow and had every mile :10 faster or more than the previous. I ended up averaging 8:28 per mile, and it took way to much out of me, for what should have been a very ez run.
