What the current slope and intercept of your fit?

Munice70.3, and IMLP
http://www.teamfexy.com

Two superfast courses: IM Florida (9:27) and SetupEvents Charleston Half (4:13). Both in 2013, both in very good form, although I crashed a few weeks before IMFL and injured my shoulder which certainly cost me minutes on the swim. But that ratio is 2.24, which suggests that I'm underperforming in full distance races, which I think is absolutely true. Back then, I was consistently 1:28 run split in 70.3, but I've never managed better than 3:35 in the 140.6.

Sadly, 47 is turning out to be much harder than 43 years old. Today, I'd do just about anything to come close to those performances again. Seriously depressing.

Updated. With 35 points and corrected bike time for Sean H, we've got

Slope: 1.94995374158 Intercept: 77.7876372151

Any run that doesn't include pooping in someone's front yard is a win.

Next races on the schedule: none at the moment

So for us non-mathers, is the formula estimating F=1.95(H+47min) ?

Oui, mais pas de femme toute de suite (yes, but I am not ready for a woman straight away) -Stephen Roche's reply when asked whether he was okay after collapsing at the finish in the La Plagne stage of the 1987 Tour

Half 4:50 (Redman, OKC) usual time is between 5-5:10 for other half's. Course is about as flat as can be and pretty easy as long as weather cooperates.
Full: 11:30 (Ironman Boulder) Only full I've done so far.
Ratio of 2.39.

F = 77 + 1.95(H) (in minutes)

Thanks, that works much better. That was the formula that I originally tried, but converted the Intercept as portion of an hour.

I had no idea I am the slowest HIM finisher on ST.

And thank you for doing this. I always wondered about the 2(H)+30=F estimate. Now we know there's a better way.

I don't know if this data point helps you, but here you go:

Half: 4:58
Full: 14:26

Ratio: 2.90

My excuse for the full is that I had a terrible race plan and walked the marathon. I'm doing it again in August I'm I have a much better idea how to do things. I'll report back if you are still looking for data.

Amateur a lot of things, professional a few things.

Wow. While basic math, that's still pretty impressive. Accurate within 8:30 for me the one time I did a half and full on the same equipment in the same season.

Even better with Slope: 1.94995374158 Intercept: 77.7876372151

Hooray Math!

28 minutes slower than my "double half", both races on similar flat courses (Galveston 70.3 and Arizona full). I'm pretty sure that if I raced that same half in the shape I was in for the full, that I go sub 5, but that's just a guess.

What's the slope if you force a 0 intercept?

The current formula implies that all competitors are treated equally: that the 77 mins applies equally to pros and 17hr finishers alike.

In fact, since pros complete the course quicker, this 77 mins is a greater proportion of the total time - implying that the cost to double the distance is a greater time burden to the pros than the midnight finishers.
