My situation has been a bit different from all of the above so far. I have been splitting my time between the UK, Austria and Colorado for the last few years. I am about to graduate with a Masters in Neuroscience in May, and then everything will change.
I went on holiday a good few years ago with Mountain Edge and after enquiring a little bit, I was offered a job as a Mountain bike guide based on
1. Fluent german
2. getting all the qualifications
3. being a good bike rider (race elite XC) and easy to employ
I worked 3 summer seasons from May til October with Mountain Edge, Living in Kitzbuhel, Austria for the summer and then coming back to England to do Uni. It worked really well, and I would suggest doing it part time is the only way you would afford to be a guide,as theres nothing to bring in money in the winter.
Last year I got offered a work placement in Colorado, which I jumped at. So I lived in Boulder Colorado for a year whilst working in a research lab. Now that I'm graduating in May, I will be going back to Colorado to take up a more permanent position as a researcher, thus allowing me to live in the mountains, get paid a real amount of money, and still ride my bike/snowboard every day. I would much prefer to go back to Kitzbuhel and be a bike guide for the rest of my life, but unfortunately its just not a viable trade without the associated holiday business attached to it.
If you ever get the opportunity to move to the mountains, no matter what the circumstances, take it! Just have a plan if you want to make it long term.
