A colleague is having some time off and i have taken over his class for 12 weeks for four days a week, as well as stepping in as acting head teacher. The age group is older than my usual class, although not a problem for me. However, a couple of parents come into school three times a week and take the kids cross country running. i am expected to go too. Help - i cannot run,. Never have been able to. AND (and this is probably an excuse) I had three major abdominal operations last year and running really aggravates my scar tissue, which is significant. We went running yesterday and i walked very quickly at the back. i had a couple of the slowest kids with me who had to run to keep up. One of the parents had a right go at me about not running and how it wasn't worth the bother if i wasn't going to run too. Are teachers REALLY expected to be doing everything the kids do? I am dreading the next run as, really, i cannot run for toffee.
