["I was working really hard for a marathon in a few weeks but I ended up breaking my ankle a little bit ago and can't participate. I'm disappointed.", "Oh no, that's terrible. Can you walk maybe with some support at least?", 'No, I have to stay off of it completely. I can use crutches but in the heat, that will not be worth it.']
I see, that's too bad but maybe there will be more marathons you can participate in in the future.
I broke my ankle a few weeks ago and am unable to compete in a run I signed up for.
