I come from a big catholic family(6 kids)and this last week my brother said he was going to try a half marathon.I just smiled and explained to him what to do if he wants to bail.I was pacing the 1h45 group and the bugger managed to keep up with me.It reminded me of how competitive we were as younsters and the hundreds of fights mum had to break up when our game of footie or cricket went wrong. I told him that he had cheated but sectertly I was proud of him. When we got home he grabbed a few issues of Runners World and started reading. I was quick to remind him that he was still 25 minutes off my best time. He now wants to run the amsterdam marathon with me.So watch out for your brothers and sisters if they ask you if they can join u on a run.
