Over 100 students from Nottingham Vet Society will attempt the 3 Peaks Challenge by climbing Ben Nevis, Scafell Pike and Snowdon in under 24 hours on 10 March.
The funds raised will be split between VBF, the charity that supports veterinary professionals, and Medical Detection Dogs.
Online donations can be made at http://goo.gl/IkodW.
Lydia Brown, VBF President, said: "We are so grateful to the students involved who organized this off their own backs even though they don't have much free time. It augurs well for the future of the profession that they want to support their colleagues. I do hope they all make it back to Nottingham safely and I look forward to seeing the pictures on facebook.com/VetlifeVBF! "
Tom McKay, one of the students who organized the challenge, said: "We have really enjoyed the training and are reasonably optimistic we will make it back for our Easter placements!"
