It was my first Ascent last and like you, I did little to none before the race. last year the weather was perfect. I used regular running shoes. They were one of my older pairs. Teh shoes take a beat down as you go up teh MT. I plan on using the old running shoes again this year. I am from Kansas, so I am not super fast. I finished in 4 hrs. 25 min. So for the average person, running shoes work good
