Ross Carlson
Event context · see format details
In a pre-race discussion, Ross expected a tough event but thought the revised time limits were reasonable.
Community opinion; participation and firsthand experience are not established. A community reaction from a September 2025 registration discussion about an earlier DENFIT ULTRA plan in Colden, New York. Ross was responding to proposed time limits, including a revision discussed by the organizer; his attendance, affiliation and firsthand course experience are not established. The published venue has since changed to Cape Vincent for 2027. This does not establish the current route, cutoffs, difficulty, conditions, services or safety. No completed-race experience or numerical rating is inferred.

ultra.tortoise · 2014
Event context · see format details
The author valued the mountain scenery and volunteers’ help but found altitude, climbs and hail exceptionally demanding. Finishing the first mountain race felt rewarding.
This is a September 2014 account of Endure’s predecessor, Tommyknocker, in Woodland Park. The organizer documents later name, venue and format changes. It is historical event-lineage context, not a review of the current Mueller State Park course or 12-hour format.
