In reply to pauldr:
Been a few times and I really like it. Ok it's quite short, but it's fun, exciting and a great use of the available space.
For me it's great for a lunchtime, I can ride up there, do 2 or 3 laps, finish up with a great descent alongside the ski run and be back in the office in under an hour.
And for those of you who use Strava, let me point you at this challenge

The segment is named Dallows Deliverance in honour of the city council employee Jon Dallow who has put in considerable effort to bring this project to fruition. Chapeau!
