Guided 15k trail run in Swinley forest: This run a monthly replacement to the 10K, held on the second Sunday of the month, and is an ideal as a transition to half marathon distance. It will include a variety of made and unmade trails passing through forest and heathland, over both flat and undulating terrain. It is only recommended for more advanced runners who are accustomed to longer distances. Please note: This run may be scaled back to 10km on occasion if there is no suitable Run Leader cover. As you will be running over uneven, undulating and possibly wet terrain, you should therefore arrive suitably equipped, we recommend Trail Running Shoes, and suitable layers of moisture wicking running clothes. We also recommend that you carry a light foldable windproof jacket as added protection should the weather conditions suddenly change. It is vital that all runners carry plenty of water (and gels if required) and during hot weather you should carry at least 800ml.
