Thanks for all the advice for yesterday STWers.
Ended up climbing up to Boredale Hause (more of a slog than anticipated, but not without reward!). The footpath looked tasty from the Hause, but we decided to keep it 'legal' and go for the slightly higher bridleway, and it was BRILLIANT! Lovely switchbacks at the top followed by some all out rocky tech that had our brakes squealing, and our brains working to pick out rideable lines all the way down. Grinning from ear to ear after that, and bar a couple of chicken outs on the mega drops, I think we both managed around a 95% clearance. Awesome fun.
After that we took the high route round the top of silver crag, where a couple of walkers in the middle of the path lead to my first (of 3 comedy) OTB's. Another beautiful descent though, that Craig5 did a great job on (despite waiting for me to clear the trail after my superman impressions!).
We then headed West on the lakeshore trail to the end of the bridleway and back around the low route. We only covered around 20km, but it was one of the best 20km rides I've ever done. The techy single track along the lakeshore is flawless, full of tasty drops and tight runs, and the couple of longer descents off generally stepped sections are great fun, especially on the return as you get a chance to review your lines on the way out!
I can definitely see now why this route is so raved about, and I can't wait to get back and have another go at it!
Thanks again for all of your suggestions.
