Mucky Running - welcome to the mad world of runners!! First of all, well done for actually getting out there and running in the first place. Everyone has to start somewhere, and the 5K Race For Life's are a fantastic starter.. I've done them for years myself! I only started doing 10K's this year (although I am doing my first 10 Mile race on Sunday!!). I know I can do the distance, because I've done it myself on my own. In a 'race' situation, you can usually run further than on your own training runs, because of the atmosphere and the encouragement of the crowd. I would suggest that you 'up' your own training so that you know you're quite capable of running 10K (do not worry about times!), and then find a race local to you - (if you like, you can find out how many entrants there are, the more entrants the more non-elite runners!) - and then go and do your best and enjoy it - whatever time you do it in, will be a PB anyway! Good Luck!!!
