text: Although a sled drawn by 20 reindeer will cover no more than 20–25 km a day (compared to 7–10 km on foot, 70–80 km by a dog sled loaded with cargo and 150–180 km by a dog sled without cargo), it has the advantage that the reindeer will discover their own food, while a pack of 5–7 sled dogs requires 10–14 kg of fresh fish a day.
