Just as I started my 1st 90 sec run kiaput!!!! Could have hung up the boots there and then but thought no I've made the effort ( left the 4 kids with hubby) can't give in. Completed it to the best I could with trying to count, concentrate on not collapsing and hoping my maths was right on the number of 90 sec runs I should do!!!! Ipod recharged for run 3 in the morning so hopefully Laura will get me there!!!
