Good to see you back on the bike.
For a while there, I thought this tri stuff was a mere transition to the swimming forum.
Speaking of which, are you re-considering Brittas Bay or still doing the OW swim?
Very much Tri oriented, Izoard, its just that lately back and knee problems have kept me off the bike and trails. Plus I look hot in speedos; not so hot in gay compression socks:)
I've deferred the Sporting Proud Tri until next year, and am doing the Glendo swim. I'm swim fit, and nothing else, so that takes care of that. Pity, I'd like to do it, and I reckon the distance would have be perfect to have a showdown between the both of us
. Best of luck doing it! 0 -

Make sure to adjust the time upwards in the excel sheet for that one 0 -

I know....I should have typed it in pig-latin, she'd never know what the heck we were talking about!!
Question for you - as I was blazing down the mountain Wednesday night clocking a 6:xx min/mile :cool: (if only I could replicate on flat land....<sigh>...) I had two bottles of water (uber-cool donut shaped ones that fit nicely in your hands - part of the Achill half marathon gift bag) - one in each hand (usually I either carry none or only one) and I noticed the slight addition of weight, especailly when my arm pump became faster as my stride became faster, and I wondered if the additional weight was actually benefitting me going downhill - did the slight extra weight in my hands allow my arm action to have a bit extra pizzazz??0 -

Hmm... I'd say better arm action was feeding into your overall stride and form, more so than gravity sucking the extra weight downwards at a faster rate. As a swimmer you should be using your upper body as part of your overall running motion anyway- maybe this is something to pay attention to on the flat? (you probably do anyway)
(Nerd answer- If you are on top of a hill, holding a liter of water (= one kilogram- see the benefits of the metric system?;)), your {body+water} system holds a certain amount of Potential Energy. Lets say you are 50m higher than the bottom of the road you will run down to. Your potential energy is PE=mgh
PE= potential energy
m=mass
g=gravity=9.8
h=50m
Lets say you weigh 60kg, so you have PE of 61*50*9.8=29,890Joules. This energy is released by the time you reach the bottom of the hill, so its been part of your downhill effort.
Without the water, your PE is 60*50*9.8=29,400J, meaning you require more energy inputted (effort) to reach the base in the same time. Therefore if you carry enough barrels of water to the top of your hill, you'll soon be running down at the speed of light.
There may be minor flaws in discounting turbulance, friction, and other limiting factors, but otherwise this exercise has been a nice diversion from Group Theory;))0 -

I converted the 60kg to pounds and was like :eek:. Shave 8kg off that and we're talking!!
I actually don't pay attention to my arms most of the time when I run, but that's a very good point - I will do that this weekend.
I certainly knew about the excess weight assisting with gravity, I just felt like my arms were a pendulum (or maybe the excess weight just drew my attention to my arms) and my mind starting thinking....
As always, thanks for your perspective.

I've no real idea about body weight- we don't have scales in our house- so don't take offence if 60k is high for girls! (Reminds me of a joke I heard today, "Does my ass look fat in this dress?"- "Let me take a few steps back so I can have a look").
You've got it in one about the pendulum effect. A good swinging motion in your arms will feed into a longer stride, and a more dynamic running form. Maybe the water bottles "forced" your arms to swing parallel to your direction? That's efficient, but often runners when tired will swing their arms across their body, and that's a loss of momentum. Everyone's different though, I know some really good runners whose elbows would take your eyes out if you ran beside them. But no harm if all this gabbing results in you considering your upper body form for running.0 -

Well done and super job keeping the effort high. I assume since this was a "swim only" that it probably attracted some "real" swimmers which makes your placing even more impressive than it already is. And blazing time - 25 minutes is really awesome - and so glad you had a grand day.
