I Require ENERGY and Lots of It!

Caffeine is a stimulant used by the bucketload in competitive sport because...

It prevents the action of a hormone called prolactin (released by the pituitary gland) that gives people that 'knackered' feeling when exercising.

Tests of muscle fibres via biopsy indicates that - when feeling bushed - the muscles are still packed to the gills with energy/etc., and notionally still good to go. The prolactin is the body's way of suggesting you pack up and go home before damaging something.

Just checked the first few journals that popped up on Science Direct (searching for "caffeine endurance") suggests improved performance in running time trials (around 1.5% time reduction over 5km) for trained and recreational athletes. Also, a significant reduction in experienced leg pain for cyclists... so caffeine is good.

As such, stoke up with the IAAF's maximum blood content of caffeine (last time I checked, it was 300mg/l) and enjoy the extra mileage it provides. Do bear in mind that the extra workout will need that much more recovery, too.
 
I drink about 3-4 cups of coffe a day. Thinking about swapping my sugar for honey though.

oh - I'm about 8-9 cups of coffee a day - and I don't measure it either ! :(

that said - it works .... lol - no sugar or anything, or milk, just black.

re letarghy a lot of it is in the mind .... I've had evenings where I've been so tired I fell asleep before gym - for 40 mins or so- then woken up and thought can't possibly go ....

2 mins later .. ok perhaps I'll go but just do a light session .. drive to gym ... start.. continue ... continue ... 10k later ... oh I was tired earlier

a lot of it is mind over matter/mind games
