After weeks of training, it is time to slow down, because it is important to be well-rested, with fresh legs and a full tank at the starting line. In the final week, it is common to run about half of the average number of kilometres you’ve been running in the past months. In percentage terms, the share of high intensity remains more or less the same. Do not do any heavy training in the last 3-4 days. Just skip the strength training for a week. You can continue doing easy core exercises.
