For their remarkable efforts Gannet Beach Adventures has sponsored the girls' entry fee and has also given them a T-shirt each to wear during the challenge. Gannet Beach Adventures managing director Kim Lindsay said they were "all determined girls and are very capable".
While the girls take part in other sports such as netball, soccer and orienteering, their teacher David Barclay had rustled up lots of support when it comes to stepping up to a sporting challenge.
"Their teacher this year is very sport-orientated, he really pushes all the kids to give things a go," Mrs Lindsay said.
The girls are the youngest team to enter this year and said that they were nervous but very excited to be taking part in the challenge.
