When temps stay above freezing overnight and throughout the day, the snow base doesn't hold up very well. In 24 hours the adequate conditions of yesterday yielded to crap. Lots of slush and lots of sliding described my outing today. The wet, soft snow made for lots of extra work. A week ago I lauded how nice the snow was for faster running but today was a complete 180°. Sliding to the side, sinking deep, running through slush...yuk.
