In reply to flopsicle:
I totally get your problem. I absolutely hate running on streets/ on streets at night. I much prefer doing cross/fell running because there is always something new to see (nature, copulating dogs/cows
).
For the more boring runs get yourself a mp3-player, load it with your favourite music to keep your mind busy.
I am pretty sure that you can do a 10k. Just set yourself a realistic finish time and don't be disappointed if you go over by a few minutes. Take it as an experience, I'm sure you will like the atmosphere on the race day.
Maybe doing the run is a trigger for you to train properly for the next one, improve your time, etc.
An injury is, in my opinion, very unlikely. I mean, if you get too tired to run, then just walk a little bit and start running again when you feel like it.
I did the Manchester 10k a few years back. found it very expensive and crowded. it is a nice run if you like seeing hairy blokes in ballerina costumes though. the finish at Deansgate is also great but I was on to run my personal best and was road-blocked a couple times by large groups of runners. Still a fun run, but the entry price is through the roof...
