1k fun runs

hi everyone, i took my little boy(22 months) down to the bolton 5k this weekend and we entered the 2k fun run together. It was for under 9s only and as you can imagine the runners were mainly 6-8. Quite obviously we finished last(come in just under 27 mins actually) My little boy loved every minute of it and was so proud of his medal leaving it on all day. Basically i was wondering if anyone knew of any toddler fun runs around that are 1k or less, my little boy loves the running around and it can only be good for him,obviously i'm not pushing him or anything(but i'll make sure he beats his time nxt yr   ) lol. We are in the north west, much appreciated
