I’ve been really stressed about my pacing for Ironman Texas.  I’ve done three Ironman70.3’s, but I have no experience with longer tri’s, or even marathons.  So I did what I usually do when I have a question…I went to the Internet!!  The place with all the answers! :)  I found this article that tells me how to calculate my Ironman pacing based on my half-Ironman times.  So here is the breakdown:

Swim - double your HIM time, then subtract 5 mins

Bike - double your HIM time, then add 15 mins

Run - double your HIM time, then add 30 mins

Total Time = double your HIM time, plus 40 mins

If I use the last two HIM triathlons, these are the numbers I’m getting

Muncie 2011:

Swim = 45:51 x2 = 1:31:42 - 5mins = 1:26:42

Bike = 2:43:14 x2 = 5:26:28 + 15mins = 5:41:28 (19.67mph avg.)

Run = 2:04:49 x2 = 4:09:38 + 30mins = 4:39:38 (10:40 per mile avg.)

Total Time = 11:47:48

Steelhead 2010:

Swim = 39:02 x2 = 1:18:04 - 5mins = 1:13:04

Bike = 2:44:57 x2 = 5:29:54 + 15mins = 5:44:54 (19.48mph avg.)

Run = 2:01:47 x2 = 4:03:34 + 30mins = 4:33:34 (10:26 per mile avg.)

Total Time = 11:31:32

Let me conclude by saying, if I got either of those two times shown above, I would curl up in the fetal position, and cry like a baby…FOR JOY!!  I have to believe there is something wrong with those times.  I am hoping for somewhere around 13 hours…there is NO WAY I could do sub-12 in the shape that I am in…right?  Any other experienced Ironman Triathletes want to “weigh in” on this topic?
