1. Keep your riding within 90 percent of your limits, give someone ETA’s and give them a printed map of your route.
2. Take a first aid kit with you.
3. Take your phone with you, although it may not get reception.
4. Take spare clothing in your bag in case you get stuck somewhere, people throughout the world have been known to die a few hundred meters from cafes due to exposure. A lightweight bivy if you have one is a bonus.
5. Take plenty of water and energy food.
6. Wear a jacket that is high viz if you can so that people can spot you lying in bushes.
7. If you come off and hurt yourself badly, damage your helmet or bonk due to a lack of sugar do not attempt to use an escape route than involves riding technical trails….use a fireroad, blue trail or specific escape routes where possible. Only use technical routes if you really really feel that it is necessary or if you can get back home quicker by walking down them. Riding a techy trail after any of these three events is a recipe for disaster.
Keep those things in mind and have a fun time!
