Sounds interesting - it is important to work on form, keeping the arms relaxed, the stride nice and long, trying to run on your toes to propel yourself further forward.
Drills - such as high knees, bum kicks, hamspring kicks with help improve stride length and form which in turn with help knock those few extra seconds off your time!
It also appears that Michael Skinner is one of the coaches involved with the coaching day at Sutton arena, he is one of the Real Runners Coaches - he's a great guy. I would recommend anyone who is attending this course to pick his brains and watch his running style, his core is incedibly strong (he's a sub 14 minute - 5km runner).
Keep us posted on how it goes!
