Interesting topic. I think you are correct. I'm 32 and have come from triathlon which has a lot of money and executive types in it. It's not uncommon to see amateurs with bikes worth over 5k and people receiving paid coaching etc. As a big guy I'm not your average build for endurance sports and trying to keep on top of 3 sports in your free time is very time and energy consuming. Right now I'm studying for a promotion exam at work so have shelved it. I neither have the time or am able to spend the rest of the day exhausted. Golf has proved a great outlet for me, a blend of technical and social and a mental escape from work/study. I don't go home tired after a round of golf either so I can still concentrate if I am going to work or getting my head in a book. Not sure I will go back to triathlon TBH, it's too all-consuming.
