"As an enthusiastic 60 year old mountain biker, I was keen to tackle Downieville, but intimidated by the challenging terrain. Mark convinced me to take the plunge. He was incredibly patient in taking me through this amazing 17 mile run, helping me to anticipate - and then coaching me through - the most technically challenging portions." - George, Oakland
