This deceptively tough ridge top trail has been used for the Dirtworks series of 100Km races, based around St Albans.

Basically, your standard firetrail, but along a ridge top there's nice views to be had on a clear day. The main trail here runs all the way to Putty Road to the West. That makes for a looooong out and back though (Putty Road to St Albans is 43Km - one way!).

Climb

To be honest, don't know why I use the term, 'deceptively tough' at the off. Looking at the elevation profile here there's nothing deceptive about this at all - 300m elevation change from St Albans road is going to be hard!

And once you're up on the ridge, don't think for a second the grinding is over. The undulations give way to a couple of nasty little peaks with first a 50, then 100 vertical metre peak to climb.

Heading North, be sure to take the Jack's Track turning or you'll end up at Putty Road to the West. Besides, there's the crazy descent down Jack's to make the struggle of the ridge worthwhile - 200m vertical drop in a little over 400m distance!

Return

And when you're done, well - how to get back to the start? For the insane, turn around and ride it all in reverse. Personally, I'd rather take the road route stopping by The Settlers Arms pub in St Albans on the way
