Hi guys. I`ve just gone back to running after 8 months of a bad back.I was never that good anyway.(PB at 10k 60mins) Anyway I have just entered the brighton 10k..very flat...in 5 weeks time. Should I try to train faster on the flat or should I work slower, shorter distances on the awful hills I have around here.. or does it not really make much difference wlth so little time to go? Really hoped I would break the hour this year but don`t know if I can now.
