Although they ran quickly, they were still not making enough progress
I was snowboarding down Mt bulla and I looked beside me and I saw two people in the distance snowboarding too. A few seconds later, I saw an avalanche. The avalanche kept on picking up speed and the two people snowboarding next to me couldn’t out run it. Although they ran fast they were still not making enough progress to out run it. Suddenly the avalanche slowed down a little bit and then they just managed to out run it.
