Together, you can do a warm-up and a delay for a couple of kilometers (for an adult, this will be an easy option before / after the main work, and for a child - a full-fledged workout), short accelerations, exercises to strengthen the feet. While an adult does speed work, children play moving games (not on tracks, of course), long jump and engage in other activities - there is usually enough space in the stadium. A good opportunity to combine a full-fledged training and a high-quality active walk, especially relevant for schoolchildren.
