The race was on Saturday 18 April 2026 and moved to the downtown core that year, with Nathan Phillips Square as race central. The finish is the same spot as the TCS Toronto Waterfront Marathon’s finish line on Bay Street. Runners used the three westbound lanes of Lake Shore Boulevard West before the turn and the eastbound lanes coming back.

Each runner found the corral by matching the colour of the flag to the coloured stripe on the bib. Portable toilets stood on course at about 2, 4, 6 and 8 km, with water and electrolyte drink on course and at the finish.

An invisible layer before the start keeps seams, straps and shoes from rubbing skin raw.

Put it on before you leave for the start: heels and toes, inner thighs, under a bra or heart-rate strap.

Try it on a long run first, like everything you use on race day.
