I have used a similar training log since 2005 and have kept and compare my training logs from time to time to see how things have changed. The training log that I use includes training zones for each discipline; from Anaerobic Threshold, Heart Rate Reserve, and running pace zones to Functional Threshold Power, Power Profile and Race Zones on the bike. This additional data requires additional testing and a bit more complex for a simple training log.
