You have reason : training for peaking in the most important event of the season (for example, WCh) is very different from training for maintaining a level of shape around 90% for long time.
For example, with Imane Merga we had the goal, in 2010, to win Diamond League, in 2011 to win World Cross Country Championships and to get a medal in WCh in Daegu.
For winning DL, we needed continuity and consistency, but really (also if Imane improved his PB) never we looked for peaking. He was able to improve his PB not because peaked, but because some competition of DL was fast and well rabbited (something normally not possible during big Championships).
Here we can see his competitions of DL (2010), all in 5000m:
14 May Doha 13:05.20 (3)
04 Jun Oslo 12:53.81 (1)
10 Jun Rome 13:00.12 (1)
03 Jul Eugene 13:00.18 (3)
10 Jul Gateshead 13:00.48 (3)
06 Aug Stockholm 12:53.58 (1)
19 Aug Zurich 12:56.34 (2)
In the middle of this calendar, Imane had also to run in Nairobi (1st Aug) 5000m during African Championships, but was under heavy training (5th in 13:41.98), because after Gateshead we needed to have a period of tough training again, enhancing the mileage and doing some specific session of intervals on track, at medium speed (between 2:35 and 2:42 per km, using distances from 600m and 2000m), and the last hard training was carried out on 28th July, 3 days only before African Championships.
In this case, we need to alternate blocks of competitions (twice in one week) with 3 weeks of training, looking for a modulation allowing the athlete to stay at 90% of his max shape for several times.
In the case of peaking for some Championship, we need a longer period of preparation approaching the most important race, and we can compete as qualified training, but not to use too many nervous energy in the competition.
For example, in 2011 we had different goals.
During winter, the goal was to try to win WCCCh, because the competition was in Spain, on a dry course (practically almost like track), in the best conditions for Imane.
He never competed in Winter, only tough training till Ethiopian Championships, when he ran only for qualifying, without peaking. Only after Ethiopian Championships, we had about 4 weeks of specific training, and he won WCCCh on 20th Mar, without struggling (also because of the bad shape of Kenyans).
During the track season, looking at WCh in Daegu, his activity was reduced, compared with the prtevious year :
26 May Rome 12:54.21 (1)
03 Jun Eugene 26:48.35 (2) PB 10000m
30 Jun Lausanne 12:59.47 (2)
10 Jul Birmingham 13:07.63 (3)
22 Jul Monaco 12:55.47 (4)
After Lausanne, Imane started the specific preparation, looking at more volume because the main event in WCh was the race of 10000m. With this training, and not specific speed for 5000m, he went Birmingham and Monaco, "using" these competitions as preparation.
In Daegu, he was almost in top shape : at first, won bronze medal in 10000m on 28 Aug (not able to beat Jeylan and Farah, running last lap in 52"7 and 53"), and probably could have chances of silver if the race was paced in faster way. Four days later (1 Sep) won his heat of 5000m in 13:37.96, and on 4 Sep ran again at his best level the final, reaching the podium before being DQ because ran some meter out of the track during the first turn of the last lap (big fight in the leading group).
The shape was so good, that we decided to try to win again the DL, and he went Bruxelles (16 Sep) able to win in 12:58.32.
So, at the end, Imane won twice, but with very different approach, and of sure his shape at the beginning of Sep 2011 was better than the shape of 2010.
