Depends on what your idea of technical is? Some people think going into woody trails with a few roots is technical no matter how “technical” they actually are. This is all down to what riding they normally do and how much of it. Last year there were a few teams made up of roadies who had never done off road. But dam they were quick up the hills and awful in the woods.
Best advice I can give is treat this one as a learning experience and don’t expect too much. You will find adrenaline will take over at the start and you will run too fast. Then wish you hadn’t half way round the first lap. Lap 2 and 3 will start to get quicker as the pack spreads out and then 4,5 and 6 will fly by. 7 and 8 will see you starting in the nite and wonder what the hell you are doing. 9 will see you want to give up so you may stop for a few hours, 10 will be a blur and 11 will have your body sensing the dawn and hear the birds in the trees. 12 will be your favourite lap as the sun is on the way up and then your on the home stretch. 13 and 14 will hurt and if you can manage more very well done.
All I can say is enjoy it and if you have a friend doing it solo too, stay with them and also chat to other riders as it makes the pain go away as you can concentrate on getting words out rather than “MY ARSE HURTS”
