Dave Smith includes in his programme a serious of workouts of 800m repeats with a 200m jog recovery to prep for the cross country season. In July for example the workout would be 10-12 x 800m in 2.30 with a 200m jog recovery and the other 'workout' for the week would be 60 minutes steady running followed by 10 x 200m in 30-31 with 200m jog recovery. This would progress to 10 x Mile in 5.10 down to 4.50 on a trail, and then 5 x Mile in 4.50 down to 4.10-4.20 on cros country.
