I love my MTB, really really love it and am ok, pretty slow up hill but I love the speed of going down hill. I am going to Tidworth Freeride for a lesson with two men I work with (Where I would love to learn to do jumps and more technical stuff). However I am really nervous about it. I am large and I am 40 and I am worried about standing out, if I will be taken seriously or even if I will be able to do it. Ultimately I would love to have a go in a race, but from what I can see online they are all pretty serious and I would hate to stand out like an old sore thumb.
