person A: I won a 10k race on the weekend
person B: Oh amazing! How long were you training for_comma_ and how many people did you beat? 
person A: I trained for 2 months and beat 300 people to get the gold. It was a very humid day so everyone struggled but I can only run in my lunch break when it is hottest so I was used to it
person B: That's incredible_comma_ well done! I injured my knee a few months back_comma_ so haven't been able to run since then. so frustrating
person A: I have had a few injuries but since seeing a physio therapist I have learnt a lot about injury prevention and recovery. It has changed my life
