One thing of note: Course record for Goucher #usarc

Thanks...good stuff !

High schooler Alana Hadley finishes in 1:17:01 #USARC

Kara Goucher is your 2012 #USARC Half Marathon Womens Champion!

Goucher has increased pace, now predicted to finish under 1:10 #USARC

Don't believe the tracker. It was Abdi followed by Brett.

Reports from finish line saying Abdi beats Gotcher by 1 second #USARC apologies about incorrect info from athlete tracker

Still waiting on official results for men, going off athlete track which has Gotcher with the faster time #USARC

High schooler Alana Hadley slowed to 58:47 thru 10 miles 1:16:35 pace #USARC

So Abdi "or" Gotcher...2 winners !

Alana was 31st overall and the 11th American back in March at the NYC Half when she went 16:46

1:02:39 for Gotcher! #USARC waiting on official confirmation on the win for Gotcher

1:02:47 for Abdi at finish #USARC

5:18 / 53:35 for the women. Goucher leading by about 18 seconds.

Abdi pulls out the win! Working on getting post race interviews live right now.

Goucher opens small lead on Krifchin #USARC

High schooler Alana Hadley still on sub 1:16 pace at USA Half Marathon Champs; would be WR for age #USARC

56:58 at 11.9 miles for Abdi #USARC

The #USARC Half Marathon Champs are heating up! Join the conversation here:

Melissa Johnson-White is on 1:12:40 pace

Alana is 15 and will turn 16 in Feb 13. She owns the 15 year old world record for the Half going 1:16:41 (Feb 2012). Sub 16 pace at this point is a big improvement on that time.

Michelle Frey is on 1:12 pace

5:22 / 42:59 for Goucher and Krifchin
