Whistled round my 4.6miles in record time today. Hadn't been out for a couple of days, got up earlier and it was cooler, almost dark. Didn't get as hot as usual (pretty humid down in in Fl) and after setting my best time over the first 3rd decided to ignore my heart monitor's beeps and go above the training rate. I normally slow down at 136bpm but let it drift (Ha) up to 148. I could see from the Speedoach the difference it was making to ave pace so carried on; After 41m06s crossed my finish line with my best time so far. I got on one of these HIGI monitors at the local supermarket yesterday and it wasn't impressed with my weight or blood pressure so I think I'll up my training rate band on the watch permanently. There can't be many more pleasant ways of taking vigourous excercise than bashing away on an Edon in the early light with complete calm and the sun lighting up the horizon in salmon pink. Onwards!
