Light and breathable
Shorts or light tights, a singlet or tee, socks, running shoes and optional cap. Choose light colours in strong sun. Carry water when you normally would and take heat or humidity seriously.
Dress for the feels-like, not the calendar.
Temperature is only the beginning. Wind, rain, sun, trail conditions, effort and your own comfort matter too. These are friendly starting points, not a uniform or a guarantee.
A practical starting point
Build from the temperature band.
Check the forecast and Strava before leaving. If you tend to run warm or cold, adjust one layer. If you are unsure, bring a light extra layer you can remove.
One light layer
A tee or light long sleeve with shorts or tights. Thin gloves or a light wind layer can make the first kilometre more comfortable.
Base plus wind protection
A moisture-moving top, light wind layer or vest, tights, light gloves and an ear covering. Add reflective details and a light on dark mornings.
Warm, dry and covered
A thermal base, insulating middle or winter running top, wind-resistant shell, winter tights, toque, gloves, neck tube and wool or synthetic socks.
Cover exposed skin
Add insulation, warmer gloves or mittens, face protection and footwear suited to cold or snow. Check the wind chill, weather alerts and current Strava event before deciding.
The useful three-part system
Move moisture. Hold warmth. Block weather.
In cold weather, add or remove a layer before you become sweaty. Wet clothing can cool quickly once the group stops.
Base
A wool or synthetic layer that moves moisture away from skin.
Middle
Light insulation that holds warmth without trapping more heat than you need.
Outer
A wind-resistant or water-resistant shell chosen for the actual conditions.
Cotton can stay wet and become uncomfortable in cold conditions. Wool and many synthetic fabrics manage moisture better. Personal comfort and health needs vary, so use this guide as a starting point rather than medical advice.
Numbers worth noticing
Let the conditions change the plan.
The club is hardy, not reckless. Skipping a run, shortening it or turning back is always a legitimate choice.
Wind chill -28 and below
Government of Canada guidance classifies wind chills from -28 to -39 as a high frostbite risk, with exposed skin potentially freezing in 10 to 30 minutes. Cover skin, shorten exposure and check the official alert and Strava event.
Humidex 30 and above
At 30 to 39, consider slowing down, shortening the effort and taking extra water breaks. At 40 and above, avoid exertion. The host may change or cancel a run.
Wet, dark or slippery
Carry a light, wear reflective gear, choose traction for the surface and slow down. Trail shoes can help on wet Thursday routes. No shoe makes ice risk-free.
Local help, without the guesswork
Ask a human at BackTrails.
