I am a figure skater. It is not uncommon for competitive skaters to spend thousands, each year in the sport. At the higher end, it can easily be between $25,000 and $30,000 a year or more. The cost of coaching and ice time generally take up the most of the expenses until the skater starts traveling to and from competitions. If a skater is spending just 10 hours a week skating freestyle practice sessions, they are likely spending around $5,000 or more on ice time alone. The most serious skaters typically spend at least 3 or four hours on the ice 5 or 6 times a week. Ice fee don't account for gasoline, coaching, skates, off-ice training such as ballet, stretching, or gymnastics. Nor does this include fees for dresses, skates which typically cost $800 - $1,500 (once or twice a year), etc.
There have been times where I simply skated fewer hours on freestyle sessions and skated more on public sessions. When that is not possible (crowding, people pestering me for FREE lessons that I must pay $60 hourly for or scheduling), I work out and practice off ice or work on stretching to stay flexible. I love the feeling I get when I'm jumping or spinning on the ice and can get it no where else. I swear that when I do save enough money, I am building a rink on my property.
