I am doing a 10K in October and was following an asics plan which had me running lots of 8.5k very very slowly. No alternate rest days so I started it thinking they knew what they were saying but decided to plug in my info again to check and have got a totally different one with lots of 3k distances. Is it just a gimmick? Think I will just run fast 3k, normal5k and a slow slow 8 each week perhaps - with rests in between. Has anyone had success with the asics plan?
