The parkrun forest is the heart and the starting point of the environmental commitment, to which - we are sure - no parkrunner will want to escape.The combination of the objectives and values of parkrun is to be defined precisely because the forest parkrun/Treedom is a natural synonym of reforestation and biodiversity.Each parkrunner can contribute to the forest growth of each parkrun event.If a parkrunner runs in different cities he can plant a tree even in the forest of that city of reference.
