You just ran your personal best in a 10K. Or maybe you ran your worst 10K in the last several years.
No reason to be too happy or too upset about either situation really. I thought this post on http://www.active.com/ made the best point – what can you learn from your performance in an event? The answer is pretty simple – you can draw many conclusions that may help you prepare for the next event.
Look at your time. How does it compare to other similar events? Time is the ultimate quantifiable and deliverable result!
Consider weather conditions and how they impacted your ability to perform.
Did you feel you properly hydrated?
How was your food intake prior to the event?
These are just a few of the items you can use to measure your performance against other past performances to make for an improved performance the next time. Check out this post on http://www.active.com/ to learn more what I mean -- http://tinyurl.com/lhmr6k.
