A different type of Sky Race ...

Over a typical Sky Race, three-day weekend, after the short and brutally steep Vertical Kilometer, there are usually 1-2 longer races.  The 32k Ring Of Steall in Scotland is one such example. As you can see in the short video, these are highly technical running races. (I have not done either long run in the Whiteface Sky Race weekend, but I had planned to do the long run in the June race at Squaw Valley, which of course was cancelled.)
