Rode 7/2-7/4/23. Had an absolute blast! Abraham Trail + Ape Canyon descent were highlights! Tire notes: 2.25" were awesome, 40 mm are absolute minimum.
Edited version of a Dark Divide loop -- used "2022 Summer 300 km Brevet -- Three Volcanoes 2.0 (final)" route to reroute SE out to Trout Lake and NE out to the PCT.
