Now checkpoint Pelly Crossing has been reached, marking the 300 miles of the Yukon Arctic Ultra. Temperatures have risen considerably in the Yukon up to -15°C (5°F). While that is a relief temperature-wise, it might also lead to the dilemma of finding the appropriate clothing (number and composition of layers) and also might lead to a softer trail which can become very cumbersome to travel on. The previously very low temperatures have taken their toll also on the study-participants: so far four had to scratch leaving four to be still in the race to reach the finish in Dawson City.
