A friend rode in front of the lead man in the Crim 10 mile about 5 weeks ago and noted the runner was a LONG ways from running the SPR. In fact, he dropped back a time or 2 to suggest he follow him to run less distance. The runner, who missed the course record by 10 seconds, failed to listen. I've noted this among leaders on a regular basis: they're more interested in the race, than the pace. If the leaders aren't tuned in to a nominal distance, it's unlikely the masses, on the whole, are any better informed or interested in running the SPR. Those w/Garmins find the extra distance added to their final total, which is typically 1 part in 100 long already. And so it goes & goes...
