Anyone telling you to MTFU isn’t worth listening to…
If you can picture yourself riding it from the top, then you probably can. If you can’t then it’ll just be a case of luck if you get down in one piece. If you stop at the top, put a foot down, start again, set off on the saddle rather than on the pedals balanced evenly over the bottom bracket, sitting tall because you’re scared of smashing your face up, arms straight to hold yourself away from danger, stiff, wobbly, put a foot down, wobble more, front wheel catches, wobble more, big off and it’s not going to be a nice landing.
Reading and practising the content of Mastering Mountain Bike Skills 2 or going for a skills day will turn it from fear and avoidance or MTFU stupidity and a potential trip to hospital into a controlled and fun experience.
