Wow, Derek! That sounds like a great race to me! If it wasn't your best time, what is your PB for 10K? Did you run this race last year? And if you did, what was your time?
Anyhow, I think you did wonderfully -- and 4th place in your AG! Just out of the medals, but still good! Your AG IS very competitive!
This was my 3rd mud puppy but my first 10k in this race last two i was in the 5k. my best 10k is 44:44. Yes it's very competitive.
