Finally put my route from Sunday into RouteGadget. Comparing my route to those faster than me, it looks like a big part of my slower time was that I elected to take straighter, cross country routes on 3 legs.
#2 - definitely cost me a lot of time versus the road route, I don't recall the route being particularly slow or having issues, but road would have definitely been faster.
#5 - going straight in the first part of the leg definitely cost me some time - piney woods generally uphill slowed the pace...
#6 - climbing in woods versus on trail.
Rest of course I was proportionally slower, mostly due to lack of fitness.
