When talking about Radcliffe it's important to note not that she just moved up from world class track (and half-marathon) ability to the marathon, but that just three months later she's gone back down to the shorter distances and run faster than ever.
Kristiansen set WRs in the 5000 and 10,000 after a marathon WR (although a year later) and I think Salazar had a pretty good track summer in 1982 after winning Boston Marathon. Probably some others have done well on the track after notable marathon. But I think Radcliffe's ability go move up and down and maybe back up again over a wide range of distances in such a relatively short time-frame is exploring new territory. -----Original Message----- From: alan tobin To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: 8/1/02 1:46 PM Subject: RE: t-and-f: women's AOY Someone correct me if I'm wrong but I believe the energy system usage for a marathon is something to the tune of 99% aerobic/1% anaerobic. The 10k is 95% aerobic/5% anaerobic. The 5k is 90% aerobic/10% anaerobic. The 3k/2mile is 80% aerobic/20% anaerobic. The mile is 60% aerobic/40% anaerobic. The 800m is 50/50. I think those numbers are correct, or at least close in terms of energy production system. I'd say the 3k/marathon is in the same ballpark. George Young was mostly a steepler and he made the Oly Marathon team. Another George who roams the list was also a good steepler/marathoner. The difference between training for a marathon and training for a 3k basically comes down to what you do in the last 8 weeks or so. Most likely you're still going to be putting in heavy miles for both and you're still going to be putting in hard aerobic miles for both, the difference comes in the final preparation and a few other small changes (heavier miles/longer runs for 'thon...working on pure speed/form year round with 3k). Take a look at Lydiard's training schemes for example. He had all of his runners running basically the same until the last 5+ weeks.

The difference in distances (42k is 14 times >longer than 3k) isn't a good >yard stick. > _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com
