We went at the start of the year as a family, and we each had varying degrees of success, Kate of course walked out onto the ice as if it was as easy as walking, and I struggled a bit, but got on reasonably by the end.
Today we decided to go again, just the two of us. Kate again had no problems from the outset, but I took a few circuits to get going. By the end of 3 1/2 hours I was getting on pretty well, although I'm sure like the kitesurfing it looks a lot better to me than any spectators.
I can go pretty well in a straight line, striding nicely, and round the corners still could do with a bit of work, but getting there. No way of coming to an unplanned stop yet, just aim for the side. Getting a bit better at skating around obstacles, but still able to crash into them if they are completely unexpected.
Clothing - couldn't quite remember from the last time, but my recommended clothing would be jeans, tshirt, light top, gloves and a hat. It's a pretty warm activity, but its cold on the hands and head.
Felt it in my legs today too, although not too bad now, sore ankles where the skates were rubbing a bit, and my Achilles on my left is really sore, a super workout for the legs. Also, not nearly as risky injury-wise as I would expect. I saw some people falling pretty hard, and nothing bad to report. Far more likely to get far worse injuries on the water :)
