Anything is possible in life. Something could happen to me where I can't run anymore. In which case, I will likely take up cycling.
That said, someone who is basically my running mentor right now has has been running marathons for 30 years (he's 58 years old), and, as an example, was 11th place last year in a marathon that had several hundred of runners. No sign of slowing down. The simple fact is, this is the running future I hope for. (And there are a lot of examples like him!)
