Not sure if anyone has overcome a fear or phobia, but im doing an adventure race in september and one part of the course is to run up a mountain 751m and check in at the top, the only thing is I am shit scared of heights like I have been to the top of the empire state and held the inner rail, went to the top of the 7* burj and stayed in the elevator ...... its a strange one though as the bit that gets me is the edge ....I went up two mountains so far but stop short of the top one was 480m and another 580m the legs go weak and even though im in no danger the fear of falling sets in .....no hassle getting down .......Im doing the race its already mentally finished in my book ......but how the **** am I getting up to the top of it ???
