Tunnel Hill is a rails to trails path. Flat or steady 1 percent grade. Faster than a flat road course because of the softer, crushed limestone groomed surface. Protected by trees, so negligible wind. Perfect conditions today. Not a true trails race. All world records in the future will be set at Tunnel Hill.
since when is a "softer, crushed limestone groomed surface" faster than pavement? it's not faster at 25 mph, it's not faster at 15 mph, and it's not faster at 8 mph.
I don't know about the surface of this particular route, but in my experience running on a softer surface beats one up a great deal less than running on pavement and this probably matters more the farther the run. In particular I ran the NCR trail marathon a few years back and my condition at the finish and subsequent recovery went a lot better than any road marathon I've run. It's entirely plausible that this trail is faster over 100 miles than pavement simply because it is less damaging to the runner's muscles.
In any case congratulations to Camile on a job well done.
