Ran a 10k this past weekend and got smoked by a 13yr old, he ran 33:50 for 10k. The course is an out and back so you actually get to see the leaders, pretty impressive to see this kid towards the front with all the big boys. He does hold the national record for his age group at 3000m on the track and I would imagine this would have to be very close to the national age group record for 10k road race but they just keep under 19 records instead of specific age groups for road racing.
