dr g i have done the yasso thing,though i haven't managed a full set of ten yet! and i think it works,but this was part of the sub 1.45 runners world half marathon schedule which i am keeping half an eye on ahead of windsor.am deeply embedded in noakes' lore of running at the moment and am getting terribly confused over different training methodologies....so after windsor i will probably go back to the 4 hr rw marathon schedules and see if it looks sensible...
i enjoy track sessions but its a bit of a fag getting to the nearest one at work-15 mins on the tube each way + changing time,so unless i can readily get a 2 hour lunch-in which case i'd rather do a 10 mile run-i don't tend to use it much any more.the other factor is that with a timex gps thingy,the whole world looks like a track(especially bits of docklands i can run to as a warm up)....you can set it to peep at whatever interval you like...and i'm also trying to get some value out of my gym membership at the moment,and when it was vvv hot,the air con was a joy,and getting the pacing spo6t on with a treadmill helps...now there's a bit of fresh air about i think its a shame not to take advantage of the great outdoors...
