Paris Brest Paris (PBP) LFGSS 2011

There and back (as about 350km) will be very good training for day 1 of PBP.

Most people on PBP will have a 7pm-10pm start and you'll be unlikely to have built up enough of a time buffer for sleep until the second night, even then you'll only be grabbing a couple of hours.

Even if you knock off the first 450km of PBP in 27 hours (by 10pm hopefully) you've only got about 3 hours in hand. The timings are slightly skewed in that you've only got 40 hours to do the 600km to Brest and then 50 hours to do the 600km back.

I'll probably end up heading back out across Suffolk and Cambridgeshire until I get too tired and hop on a train to Sheffield.
