On the advice of my Slovene physio, I had a training session of Nordic Walking last week on Parkers Piece.
Nordic Walking originates from cross-country skiiers wanting to practise during the Summer. The poles are much shorter than for skiing, but some of the same principles apply.
It's surprisingly easy to learn the (very) basics. It's an odd sensation when you're walking. You seem to walk slightly faster than normal, yet it feels easier than walking normally. (You put very little pressure on the sticks, so it is a little surprising.) The interesting fact is that you burn a lot more energy compared to standard walking (around 40% more). I'm doing it because it also forces you to equalize your stride - something that you *don't* do when you have an arthritic ankle:-(
So, if you see someone on Madingley Road looking like this, it's probably me. [When my daughters are teenagers, I might have to stop!]
