On November 31st a group of men will challenge themselves to climb 3000 ft to the top of Lugnaquilla mountain in Co. Wicklow to raise funds for men's mental health issues and men's cancer.
They're calling the event LugMOquilla - because it's being run as part of Movember, where men grow mustaches all through the month of November.
Last year was the first year for the event, and it raised just over €2,000. 17 ordinary men with no hiking experience climbed through minus 18 degrees wind chills and heavy snow to reach the summit.
If you'd like to donate to or get involved in this year's climb, find the group on Facebook or on Movember.com.
