From 10:16 am on October 28, 2019 until 1:03 am on October 30, Bob Durie and I completed all 11 loops of the Frontenac Challenge as a thru hike, starting from the Big Salmon Lake parking lot. The total distance for an efficient thru-hike is somewhere around 102-117km and the order we did the loops in was was inspired in part by Sara Montgomery's 2016 3-day Frontenac Challenge route, that she completed using car shuttles in about 54 hours. Here's the order we ended up doing:
Day 1
Big Salmon Lake
Slide Lake
Little Salmon*
Little Clear*
Hemlock Lake*
Tetsmine Lake*
Camped @ site 11B
Day 2
