So she's doing this run, 10k and I'm really concerned she's not prepared enough, she can easily run 5k and has recently done 8.5 k but not 10 yet so it'll be her first run 10 k this weekend.
I'm so scared she'll put her body under a lot of stress, stress she's only young but I'm really worried.
There's always someone collapsing or worse at a marathon, even though I know this isn't that far.
