The team finished the event in 9 hours 6 minutes after cycling 47 miles, ascending Pen Y Fan and canoeing across Pontsticill Reservoir.
A fantastic achievement for Jason Brookes, Jon Bridgewater, Andy Seeley and Steve Roberts.
This is the third year in a row that Widney has taken part in the challenge raising almost £10,000 in total for the children's charity Action Medical Research.
Action Medical Research is dedicated to funding research to help reduce the rate of premature birth and improve treatment for sick babies.
