My gradual build-up of ego-free mileage has gone slightly sideways. Weeks of 90 and 94 kilometres have been followed by one of 72. I'll call it whispering sideways, in deference to Lorraine Moller's story in the November 2010 issue of Running Times: Becoming a Body Whisperer. Moller talks about running without a watch or heart-rate monitor and tuning into one's body. I'm still wearing the Polar, but don't feel the need to look at it constantly or check the split of every kilometre.
One of the aspects of the Maffetone training I'm doing that fascinates me is the table in the 'Want speed? Slow down!' document correlating pace at MAF heart-rate on the 5-mile MAF test with 5k race time. I'm running the MAF test on a 10k course which isn't dead flat. I call my MAF heart-rate 130 (35 beats below maximum HR) and on 25 January ran at a pace of 5:45 per km (9:15 per mile). According to Maffetone, that would put my potential 5k race time at 22:08. In late 2007 I was running a similar 10k course at a pace of 5:50 per km at a HR of 124, which would be roughly 5:34 per km (8:58 per mile) at HR 130. I raced a 5k at Stromlo two days later in 22:25, then two weeks later on the same course ran 20:54. This is my thinking as I patiently log the kilometres: When I can run 10k in 55:40 at an average HR of 130, I should be only a couple of races away from a 21-minute 5k.
