I have just returned from a few days Skiing and found that GPS-Logit makes a fun skiing app as well. With a few tweaks that I suggested to Manfred it would be really good! I especially like the bit where it tells me how fast I am going as I bomb down the hill and then repeats the 'last run' top speed as I enter the lift queue!

I was surprised to see that the trackpoints are quite good resolution. Compared with other GPS I have used skiing, this one can actually show a lot of the turns on GE. Before it was only 5hz ones that I saw that with. The 1hz tracks were pretty random looking, but that might just have been my skiing!

I must also say that the H20Audio waterproof bag Roo recommended is one of the very best waterproof arm bags I have had the pleasure of using!
