If the Shakespear 10k is on the long Marston raceway again then it is the flattest race you will do. I ran the one in March this year and there is a big ZERO on hills, not even the slightest lump. However,,,,,,,it is windy, very very windy and to be honest I would prefer the hills. I ran this slower than the Dudley Kingswinford 10K which is hilly. If it is a perfectly calm day then it is a definate PB course.
