Sunday morning rucksack march. Do a quick warmup of pushups and sit-ups before heading out. Head out over varied terrain and try to go as fast as you can without running.
Stretch well both before and after the event. Remember to drink plenty of water and stay hydrated out there. Even though the winter weather remains among us, you can still become a heat casualty by dehydration, even before the sun comes up. And if you do it will really set you back in your preparation.
