Did this today - about half marathon distance and 1,400 ft of up - but my watch played up so I cannot be more precise. Lots of more or less level straight running, so very unfell, though there was one rough steep ascent I had to walk up. Multiple fell club vests were on display. Thanks to the RO and the marshals. The adjacent show had plenty to keep any supporters entertained, and there was a talk/tasting by Carvetii coffee roasters before the race to get me in the mood.
