My explanation is very simple : Nicholas has the talent for running very close 26:00, having speed and endurance at very high level. But, before the period in St. Moritz, his training was no more than 50% of what he needs for these results. So, if an athlete running 35:00 with 5 sessions not very hard every week is able to move to 10 sessions among which there are 2 or 3 workouts of very good level, he can improve to 33:00 or less in very short time. The proof of this is in the last season. Nicholas, disturbed for many reasons, came back to the same typeof training of before, and again ran 13:19 and 27:17, with very short period of training a very little volume.
For this year, there is an important newness for him, but you can know this fact only at the end of April. I think that this new fact can help him in finding the full focus on training, that can allow him to compete with Bekele in the next future.
