The REM is a light metro rapid transit system serving Greater Montreal, which as of the opening of the A4 branch in November 2025, consists of 19 stations spanning around 50km. See https://rem.info/en/map for more details.

This route follows as closely as possible the REM network from end to end, specifically the A4 and A1 branches from Deux Montagnes to Brossard stations, north to south. Public transit is pretty convenient to get to/from start and finish!

This route is part of the Ridge Runner trail system, and this loop is a highlight of running in the area.

As with all loop FKTs, it can be started at any point and run in either direction. The recommended start/finish is at the Noblett Lake Recreation Area, in the parking lot where the old beach/swimming area used to be. There is a day-use pavilion, as well as indoor vault toilets. Expect punchy climbs and descents, along with rocks, roots, and water crossings... typical Ozarks trail running! These are multi-use trails so you may see folks on horseback.
