loubeloo, there isn't much to Peterborough and it doesn't take long to get to Bretton from city centre. Buses run there from the bus station which is across the road from train station. I used to work at Bretton and it is fairly featureless but flat.. so PB is possible.
I can do a 10k in 49mins so I probabaly need to be a slow team too! What is the situation with forms etc do we need to fill them or will you do it and do you need some entry fees? Let me know?
