Noob HR Question/musings

Hi all
Hopefully, you can see this - http://connect.garmin.com/activity/163790953
I'm not very experienced at tracking this sort of data, but what surprised me is that my HR steadily decreased over the race (8 laps of an MTB course - I suppose a traditionalish XC course). I did nt drink enough and was cramping up something terrible on the penultimate lap and probably am not fit enough to race over that distance/time on a short, relentless, technical course, but even so, usually my HR stays constant or steadily increases over the ride/race/sportive...
Any ideas, am I just obsessing too much or is there something I can change/work on?
Let me have it!

you cant get a good reading from HR without knowing your base HR stats and to do that you need to do the HR stat tests to get a HR reading from which you can work from.
