Here are a few tips to help you prepare and there are plenty of training plans online for you to choose from.
One of the best is at Runners World.
Wear a bin liner at the start to stay warm and use the bag drop at the event centre so you have extra layers at the finish.
Wear the right shoes
Trail shoes with a good rugged tread are ideal.
Keep your eyes on the trail
Look slightly ahead, not at your feet, to avoid falling.
Keep your form
As you climb, shorten your stride, lean into the hill from your ankles and pump your arms. On the downhills keep your weight forward, lengthen your stride and keep your arms low and elbows wide.
Refuel at the finish
No need to carry water – water station at 6K. Take advantage of the food at the event centre and in the goody bag to refuel quickly at the end.
Improve your trail skills
Practice on trails and parkland and include some hill work.
Get strong and balanced
Include at least one core strength and balance session into your weekly training regimen.
Falling over on trails
It happens! Roll with the fall rather than trying to break it and you usually get up and keep going without too much damage.
The TYY is for all levels of ability. Train well, in company if you can, and have a great run.
