The questions Trail Runners ask us most. General Games questions are in the main FAQ.
Can I run two trail races?
Yes. The 5 km or 10 km and the 21 km are all in one entry, on consecutive days.
What kit do I need on the trail?
Shoes with good grip on snow is the most important. Follow the instructions from sports page.
Do I need to be a club member?
No. Winter Trail Run and Winter Swimming is open to everyone aged 30 or older. Club membership is recommended, not required.
Is there a 5 km?
Yes. On Saturday 15 January you choose 5 km or 10 km. The 21 km is on Sunday 16 January. All three are medal events.
What is the surface?
Snow-covered forest trails. Conditions change with the weather, so shoes with good traction help.
Is there a cut-off?
Yes, on the 21 km, to keep the race inside the January daylight. Times are in the regulations.
Can I add another sport?
Yes, up to three sports on one entry. The trail run finishes on 16 January, so most of the programme is still ahead.
