Oldrich Kepka, I definitely agree that training needs variety, especially if you’ve been running for a while. Only breaking out of your routine will move you forward. Of course your training should suit the race, too. You train differently for a 10K than for a marathon. On the other hand, I don’t think it’s sensible to ride every session at the anaerobic threshold just because you’re short on time. If time is tight, I think you have to train more efficiently, but that doesn’t mean cutting out endurance work completely. I can share my Ironman 70.3 training plan and data. On the bike, what moved me forward most was lower-intensity training. For a 90 km time trial you can’t train exclusively one way or the other. It needs to be a mix. I know the saying “train slow, race slow,” but I don’t give it much weight because what counts as slow is highly individual.
