Without taking sides it seems that when my athletes discuss a race they are reflecting on what they felt happen, not on what they think happened. I can sometimes help the process by offering my two cents. For example an athlete that tries to rush transition might not realize during the race they are reacting but in a post race discussion might come to the conclusion that they did react to being behind and felt the need to hurry. I think staying on task is important but i am not sure that a rection to a stimulus could be called thinking in a race. I know I have or had at least a few athletes that run better 200's not because of the time to think but because they go into with a more relaxed feeling because the added time does not overemphasis a mistake, I am certain they are not thinking.
