1720: twin peaks but no silicon valley

Here it is in all its 7.9k glory including all the falsies and X's, two of which were never found, reducing to about 6.4 k for the sensible people who hung back and let the FRB's do the work. 1 hour 24 mins for  Aftershock and Sex Sprinter who may have been guilty of some "logical short cutting". But in truth the route left little opportunity for many meaningful short cuts unless your name was Gan Yao who successfully edited out the first and highest peak (217m) but did the rest of the run including the second hill. Total ascent was about 300 meters. The rain which greeted the start of the run was enough to reduce the 4k short run to two people, Mucky Pup and Perky. Never let it be said that there aren't any brains at the hash!
