Road shoes or a road to trail shoe. I rain a similar timed event with similar terrain wearing Topo Ultraventures a couple weeks ago and they were great.
I alternate between Topo's Ultraventure for less technical trails and the Vista for anything more technical or muddy. I like them both, but the Ultraventure with the same outsole as the Vista would be the perfect shoe.
Topo does the wide toe box. My Ultraventures have a 5mm drop, Terraventures have a 3mm drop and there is also the mtnracer model as well (haven't tried that one yet).
They are very comfortable and roomy for me with good lugs. They feel a little weird walking on pavement so mud, gravel, rocks, roots, and sand are all good but pavement is a no unless you enjoy suctioning to the pavement. If you need them to do pavement as well, look at the Terraventures which are bomb proof in durability as well. I think my husband has about 800 miles on his Terraventures with the outsole still intact. I have a lot less on mine but it should be well over 300 miles on mine and still waterproof. Terraventures come in waterproof and non-waterproof, fyi. The Ultraventure is a lot cushier than the Terraventure but both do a good job of protecting your foot from the rocks and roots.
I can not speak to durability on the Ultraventures yet as I have only put 100 miles on them but so far they are still looking like new other than the inside heel. As to the inside heal, I have to use stickers in all my shoes as my heels always rub through all shoes there so that doesn't count against them in my book (Haglunds deformation is obnoxious but the stickers are a cheap fix).
