I have just completed the Great South Run and really enjoyed it my aim was to get in under 1hr 30 mins and did a 1hr 28min so was very happy. i am about going to do a 10k in January and have been trying for some time to break the 50 min barrier. I know I need to do some speed work but need the simplest method known to man/woman or I won't have the will power to keep doing it every week. Any suggestions?Thanks!
