Do you have a medical reason to keep an eye on your heart rate?
Worrying, the course did seem long...? mine beeping before the markers too...... :-\ ??
I choose a lovely cool sun dappled forest, all alone, every time. Orienteering.
But this today, this is a challenge. Sometimes it's good to do it - and your effort paid off today! :)
No medical reason, I just find if it goes too high I run out of steam!
I chatted with several people who thought it was between 200m and 400m too long. My GPS reckoned about 10.17, and there is no way that I picked up 170m by running the long way around bends since it was already bleeping too early by the 2nd km...
Yep, good challenge, and enjoyable in a different way, and the contrast makes those occasions when you are alone amongst the trees and reindeer (or think you are alone) so much more special!
gps intrinsically can over-read. Just think what happens on an absolutely straight road and then you the 3 or 4 meters of error you get from the gps even when it's working well on every point along the gps line. The gps points want be in an absolute straight line and hence you will be over-reading. The software will try and compensate and on a none straight course the fact that the gps will cut the corners helps to compensate but gps is just inaccurate compared to a properly used measuring wheel which is what I would expect for an event like this. The intermediate km's of course may not be so well measured but I would be surprised if the full course is not accurate to within 20 meters.
Thanks Ifor. I guess if I am going to moan about GPS under-reading the distance I was running last weekhttp://attackpoint.org/viewlog.jsp/user_15353/peri...
then I should take it on the chin when it over-reads too!!!
Given the recent controversy with the Manchester marathon being under measured due to an incorrectly calibrated measuring wheel, I strongly suspect that any big profile race is going to be measured multiple times extremely carefully to avoid the negative publicity!
I think they may be over compensating for previous howlers? ;) there were MASSES of northern races under distance - appalling! http://www.bbc.co.uk/sport/athletics/36259171http://coursemeasurement.org.uk/investigations/sho...
