They generally measure short for any run if you follow the exact shortest line. the way they work means they will always have some error - less over longer races but still some error.
I get really anoyed that people belive there garmins rather than the real route.
Hi WiB I am usually on fetch mostly. St Peters way will be A Map and route description for each stage (between CPs) it is also maked with way markers all alonng the route. 45 miles is too far to put signs out for every turn.
Hey Guys, bit of a shameless plug but I have just started setting up and running races in the Essex area for Ultra's.
I am an ultra runner and some of you guys have already entered my first race the Stort30 but we plan to rune several more in the next year that will suit ultra runners of all abilities. Please take a look at www.challenge-running.co.uk the first 2 races are already on the race finder and online entries are available.
