this http://www.brianmac.co.uk/energy.htm is quite a good introduction to energy pathways and you wil see that energy does not come soley from one source at any one stage - there isn't a body switch that suddenly turns on/off
An in depth analysis of physiological functions in exercise can be found in Noakes - Lore of Running - Chapter 3 - Energy Systems and Running Performance. I would say it's a pretty standard reference book for runners and is well written although at 900 pages don't try it in one go!
funny - half the post above disappeared between typing and posting
NZC I have just had an email from friends touring NZ and seem to be constantly in rain in South Island. I have told them to head north!! There are some fast women around Now where were they when I was young
Ceal new gear - now that is long term planning!!
Some snow here and cold (for UK not Canada!!) overnight at -7C led to each step this morning sounding like a gunshot as ice cracked underfoot. Not that I had many footsteps as I had another back spasm some days back and I am learning to walk.................................. again!! Drugs help.....
Empty good to see you popping back and I hope the black dog has freed its bite on you. Family seem to be progressing well. I do hope that Liz makes it out of bed..........
Graham sounds like you have succumbed to the same bug that attacked so many thread members - it must be a virus!!
JJ Its funny how many folk suddenly need to tie shoelaces, recover things that have fallen on the floor, have a coughing fit etc when volunteers are called for!!! I have been trying to give up being Hash GM for 6 months ..................
John that's one way of involving your wife in your running - better ask permission first though!!
NZC I could get up to 130bpm on steep hills and fast walking but it would sink back very rapidly as soon as the hill load was eased.
Ceal I thought I had seen similar zones before - Lore of Running by Tim Noakes (THE definitive running book) describes the zones set out by Sally Edwards ( Ironman ultra distance athlete) in her book Smart Heart 1997 - an approach to HR training zones - 5 zones and the effects of training, and the amount of training in each.
It is in tabulated form so its a bit too complicated to reproduce here but I will send you a pdf of it for comparison purposes.
Chris I missed congratulating you on your marathon start to the New Year - that's certainly one way to first foot the year.
Back in the day when I aspired to run to a mediocre standard the Morpeth to Newcastle race of New Year's Day was always the highlight of winter running - 14.2 miles point to point, invariably with a keen wind blowing in off the North Sea!!! All the best distance runners would turn out for it and I was very sad to see its demise through H&S rules plus the slight difficulty of closing off part of the A1 for 9 miles - as if anyone was driving on New Year's Day!!!
