I’m a pretty decent swimmer, was swimming for exercise when I met 2 guys my age who were swim training as part of their tri training. We all started doing intense swim workouts and before long they invited me to join them on cycling rides. I had already done enough serious damage to my ankles, having previously been a runner out to 10 mile runs, but it became difficult, so skipped that. I ended up buying a road bike. Then a mt bike, then started down the road of serious cycling including racing a few years as a Cat 4&5. Then I started on the team triathlons and had good results with that, often placing top 3 in my age group. Eventually gave all the racing up as I realized the anxiety was stressful and I disliked that aspect. Happy now to just fun ride and swim.
