Thanks for all the tips etc above. I ended up in Tignes in the end and have had a magnificent week on the slopes. The majority of the Espace Killy is fully open – the only place you can’t get to by skiing at the moment is Les Brevieres. Conditions on piste are good but very hard snow, and there’s no new snow forecast for a while. However, it hasn’t got above freezing all week and the resort is virtually empty, so conditions have remained stable.
I got a pair of Atomic Redster ST skis from the hire shop and have been pretty pleased with them. I asked for a slightly longer pair (163cm, for my 165cm height) and they coped well with the hard conditions. They were happiest when going quickly but were by far the best skis I’ve hired for a long while. I suspect they wouldn’t do so well in softer conditions, however.
Skiing whilst pregnant was actually totally fine, once I’d got over the nervousness of the first run. It definitely helped that the place wasn’t busy (I wasn’t so keen on slopes with lots of people, but they were easy to avoid this week). I also stuck to mainly easy runs, although that was partly due to my husband’s longstanding knee injury (I did do La Face black run on the second day…). The baby enjoyed kicking me in the bladder whilst I was sitting on chairlifts though. And I have amazing blisters on my calves where my ski boots have rubbed on my slightly swollen ankles. All in all, I’m glad I made the decision to go skiing, although obviously it’s a very personal decision and depends very much on the pregnant person and their attitude to risk.
