Don't think so. But the first control wasn't actually on the route the GPX took, but instead about 100m down a side street. I took a slightly weird route there.
I finished. In time. After crashing on the ice a second time, I decided to find a route solely on gritted main roads. After crashing the 3rd time. I recalibrated on what to consider a main road, and only took roads with a N number. I made it back, in time, via all 3 controls. Battered, bruised, and with my shoes quite literally covered in ice. Now, nearly 2 hours after finishing, I've regained feeling in 9.5 toes. That was type 3 fun...
