10k single age record

Single-age (55 male) 36:51 eclipses the old record (37:05) held by Alberto Rivas since 1995.
Unseasonably warm weather persuaded me to change races from the 20k to the 10k.
I had planned an attempt to run down the 20k record 1:16.09 but I am certain I made a wise choice after seeing the 20k finishers struggle in.
kilometer splits 3:40, 3:40, 3:46,3:44, 3:42, 3:40,3:37, 3:33, 3:36, 3:35
Around 5:55 per mile.
I need another minute to beat the age-group record.
Currently hold 49 state records.
The times to beat at every distance seem so easy on paper,(based on my past performances) but they are very difficult. I guess that's why they have been in the books for such a long time.
