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 weather has begun to cool off now in the fall it is still easy to become dehydrated.
