Well done. :-)
I've always been curious whether someone could do Kringsjå to Ullevål stadion faster than the t-bane. Shortest route is 2.1km, train goes round and takes 7 minutes by the schedule. There's a lot of downhill but there's also a road crossing and the overpass bridge. It would be a good workout...
downhill sounds easy... uphill would be a fair challenge.
Thanks. Sounds like an easier suggestion than Frognerseteren to Majorstuen which has been suggested. Might have to give uphill go, match it up with the train back and do some intervals?
Inspirational. Might have to see what London's options are in the new year.
