Traditionally, Crush the Cargill challenges athletes to run up and down Mt Cargill as many times as they can within 24 hours.
However, this year, there was also the new Crush the Cargill 100-miler for runners wanting the ultimate test of their skills.
Dr Tripp said competitors would have to be fairly fit to be able to do 100 miles.
"It is a popular distance in the world and it was reasonably easy for us to put on, on top of the 24-hour challenge."
Dr Tripp said the goal was to complete 19 laps up Mt Cargill within 36 hours, a distance of 100 miles, or 161km.
Twelve people competed in the event, with three people completing the challenge.
Dr Tripp said the 100-miler event started at 10pm on Friday, so "everything about it sucks".
The next event was the 24-hour challenge, which started at 10am on Saturday.
The day’s victor was Petrus Hedman, who completed 14 laps of Mt Cargill, a total of 119km.
Each lap was equivalent to 8.5km, with five laps amounting to the same distance as a marathon.
Dr Tripp said some of the competitors had been awake for 36 hours in their attempt to complete the mammoth challenge, so everybody was "pretty tired".
A Givealittle page was set up for the event, coffee and massages were available for a fee and people were donating on the day.
The entry fee for the race was koha and all proceeds went towards fundraising for The Valley Project.
The Valley Project set up a breakfast yesterday for the competitors, who had spent 24 hours running.
