It's definitely a circular route and it might be my second fell race. Inside information from my club (Valley Striders, Leeds) is that its more of a cross country race than a fell race but can be quite muddy in parts.
If you want more information, then phone the organiser, Dave Woodhead - he organises lots of fell races in the area so I'm sure will be able to suggest the most suitable of "his" races for a newcomer
