The adorable huskies were seen sticking their tongues out of their mouths when dashing across the forest, while some others stared pensively into the sky with their heads tilting aside during the drill breaks. / CFP Photo

The Rally, which is the grandest event in the British sled dog racing calendar, features teams of two to eight dogs pulling their musher on a sled around a four to seven mile trail. / CFP Photo
