Charity cyclists to become the first all-female duo to compete in gruelling 2,150km Race Around Ireland

Former Irish Hockey International Lisa Jacob and her partner, pilot and triathlete Nikki Dorey will be the first all-female duo to cycle the punishing ultra-distance 2,150km non-stop 'Race Around Ireland' - and they are doing it all for charity.

The duo will be competing as a pair, treating the ultra marathon as a relay - one cycling for three hours and one resting for three hours.

The Race Around Ireland is part of the Ultra Marathon Cycling Association and is considered one of the toughest cycling challenges in the world.
