TWO sisters from Tavistock are searching for runners to take part in a relay run from John O?Groats to Land?s End, in aid of Comic Relief. Kathy Green, 38, and Pauline Roland, 25, have come up with the idea. Kathy said: ?This is a huge challenge and Comic Relief are really happy for us to do this. ?We are looking for a team of at least six runners who can run ten to 15 miles in a day. We are looking for people who want to take on a challenge ? we can make a difference.? The pair are already looking at the weather for next year and are currently thinking of either September or October. There will be a minibus driving next to whoever is running. When their ten miles is up, that runner will get the chance to relax in the bus until their next turn. This will continue throughout the journey of more than 900 miles. Anyone interested can contact Kathy on 07894700076.
