Pack this
- Photo ID + race confirmation email for bib pickup at the expo
- Lightweight long-sleeve or arm sleeves for ~8°C October start
- Gels every 30-45 min (4-6 for marathon) + handheld 500ml flask
- Body Glide on nipples, inner thighs, and under sports bra straps
- Throwaway gloves and a mylar/garbage-bag layer for the start corral
What you should know
- Bib pickup is at the expo in advance — no race-morning pickup, so plan travel and ID accordingly.
- Marathon enforces a 6-hour course cutoff (~13:45/mi); falling behind moves you to sidewalks and reopened roads.
- Course is a net-fast out-and-backs along Lake Shore with exposed wind sections — expect headwind on the western return.
- Gear check is at Nathan Phillips Square; the finish is a short walk away on Bay St. so pack a warm post-race layer.
- Aid stations carry Nuun and water roughly every 3km; gels are only offered at a couple of late-race stations.
