I'm in my forties and have taken to running for about 6 months. Done a couple of 10ks and am doing my first half marathon sunday (all road)! Thoroughly enjoying it but would love to try some fell running. I live in S Wales, so the Beacons aren't far. Any ideas about how the training differs and a doable first off-road race. Have read the fell-running introductory books for inspiration...but actually running up montains is ....well....any advice welcomed!
