Speedflying is a relatively new sport that has a large following in Europe, combining a high speed paraglider with skiing. Unlike my summer hobby of BASE Jumping, no cliff is need to start this type of flying. Just a steep slope and the speed generated from your skis and you quickly lift off the ground. You can choose to fly hundreds of feet off the ground, just a few inches or ever stay in contact with the snow.
I wear my Suunto Core and it came in handy recording the altitudes gained during our hikes that day, the rising temperatures reminding us to keep an eye on snow conditions, as well as making sure we didn't lose track of time.
A special thanks to Jacom Stephens for the picture.
