Experiencer

The experience you had is going to be measured by anecdote or strict wording if it is sufficiently retrieved and accurately applied.
There could be all manner of reasons as to why each experience, even a valuable one, is not vividly recalled or properly used.

The highlighted response recounts coming in dead last at a 5k. I don't know what that means, but the respondent says it was upsetting at the time then later turned out to be useful.
