This is for you statistic geeks out there like me.
I took my Garmin and my heart rate monitor with me on the race, unfortunately in all my excitement of getting over the line in one piece, I forgot to turn it off, so I have an additional 30 mins (sitting in my car chatting to my friend). Anyway taking the 30 mins out of the equation, the best I can, the heart rate monitor analyised me as working in these zones.
Fat Burning - (2%)
Aerobic - (33%)
Anaerobic - (63%)
Maximum - (2%)
What I will say is, I do need to check my max heart rate again at some point and secondly I know I wasn't at maximum during most of the race (my maximum beats per minute during the race were 192 bpm and I have recorded it up to 202 bpm on the treadmill) I think I was holding back to ensure I finished the race and had some reserve left at the end.
