For instance, the Sleep function recently saved my race day plans. I put my PB to sleep just before I went training. All the time i was out on the road I had it fixed in my stupid mind that I had left home at 1.30. When I got in at 5, I was totally gutted, as 3 and a half hours put me about 1 hour off the pace in my schedule. With three weeks to go, there was no point carrying on, as trying to make up that sort of deficit in that short time is not possible. But later on, waking my PB from sleep, thank you thank you, thankyou, the shut-down time showed first in the menu bar - 2.30. Back on track and so the pain continues! And time to sort out the stop watch function on my bike computer.
