I expected one of the week 4 runs to trip me up and thought it was gonna happen this morning. Half way through the first 3 minute run my feet felt heavy and I was dreading the remainder. It was a false alarm, to the extent that with one minute of the 2nd 5 minute run remaining I felt quite strong.
Run 3 on Wednesday then 2 day rest before week 5 ...... I predict a lot of sweat and snotters, it won't be bonnie, week 5 is the one that concerns me most I think.
