THEY'RE RIPPIN'

[joeltetreault]

One of the rabbits is falling off the back right after 10k. Two left. Quality of pacemaking could be a bigger factor than the weather.

Here's your formal abstract malmo. Of course, this doesn't change the fact that this is a strict analysis of data, which can only tell you so much....

It is 7:30 CT and it is 34ºF (1ºC) and cloudy in Chicago. I attended my grandson's football game yesterday morning at 34ºF, and, boy, was it cold.
I see that the above quoted analysis doesn't even extend as low as 1ºC. Their lowest is 5ºC, a whooping 8ºF higher.

14:33 5k, 18:41 4 miles.

Pego, do runners lose fluids faster or slower as ambient temps drop?

I'd say slower, but it's been a long time since I paid much attention to respiratory physiology.

Slower but the problem is that you aren't feeling the loss as much so have to remember to drink early and often. It doesn't look windy or wet which is what drains your energy in cold conditions. Seems like pace setting is going to be the key.

14:34, 14:38, 14: 47 first three 5k splits

thanks Lopen and Pego...

According to the Science of Sport blog, the lead pack has slipped behind WR pace as of 18k. Projected finish time is 2:04:17.

[bhall]

Will lose at least one of the pacers by 30k if not 25.

Didn't make it to 21k. Down to 1 pace setter.

Great table!

The Science of Sport blog is doing kilo by kilo updates with finish time projection:
http://www.sportsscientists.com/

They're also projecting a 2:05:55 win for Wanjiru after a sub 1:02 half, slowdown due to winds and making sure to secure the win...

but it's patrik ivuti who's a pretty high class pacemaker !!

Thought this would be handy, too.

From physiology thread...

14:34, 14:38, 14: 47, 14:49 first 4 5k splits

1:02:01 at 1/2

Sammy not taking much fluids, and seem to be doing better job of running the tangents as the pack has thinned...
