Some more Coe info ;
I am sitting here with photo copies of parts of the 84 seasons training diary, written in Sebs own handwriting. That should be first hand enough. 12 weeks during the spring that year. Average around 40 miles weekly. Most runs 5-8 miles, some steady 5.15-30 mile, some slow 6 min miles. One rest day every week. Heavy weight work (esp dead lifts, arm curls, bench and full squats)
I also looked back at my journal from 1996 when I spent time at Peter Coes house in London. We sat in his office discussion this particular topic when I asked him what Seb did at the most in the winter. He took out the 1981 schedules (when according to Coe Sr., Seb was at his very best) and showed me the 60-70 mile weeks (only a few of them that high) Not including warm ups, but most warmups were not that long and no warmups in the steady/brisk runs. So throw in there 15 miles extra and you are at 75-85 mile weeks at the most. But the workload was still incredible considering the speed combined with endurance combined with explosive element. I believe Seb is a rare example of an athletes whoes Vo2 max was not particulary incluenced negativly by all the anaerobic work (81.4 mmol/l)
If this is not enough, I could email Peter. One of few 80+ guys on the internet. Still going strong, though his sight is not what is used to after a work accident some years ago.
