My home page has a box listing the races I have run.  I have only run one 5K, but it is listed twice - once in metric and once in imperial, with both race times identical.  I must have put it in twice by mistake, but I only use metric and want to delete the imperial one as it  makes it appear as though I've done two 5Ks, and it's annoying me.  However, I don't seem to be able to delete this  - is there a special way of doing it?
