Chimney Melon 50k
This page complements the official Chimney Melon 50k page by providing the best GPX file of the course. I don't have a perfect one.
This one is marred slightly by me going off course a little bit in the beginning between the parking lot at the base of the Tram and where the path of the Tramway Trail is straightforward and strictly ascending. If I remember correctly, if you follow these tracks exactly and backtrack where I made the mistake, it'll add less than a hundred yards, so you don't have to fear that these tracks will greatly mislead you.
I made these tracks on September 3rd, 2022, doing the course on my own, for fun.
My activity is on Strava, but you're not allowed to download the GPX if you don't have an account, so here it is: GPX file
