Congrats Kawasa, that's an historic and big time race, and way to go for your PBs at 5 and 10!
I ran in a local city turkey trot, one of a dozen or so, around one of the lakes. Less than a month from the marathon not 100% and I felt it after a mile with HR spiking at about 97% Max so I ran the last 5.2 at closer to threshold effort. Just under 41 for 10K, top 20 overall and 1st in age group.
