How good is Tiahna Vladic?

Great View Right - Look at the spectators trying in vain to see the rest of the field

Ok so we saw Tiahna Vladic (US# 15 for 5k- - -US# 13 for 3 Mile)for the first time last year when she cruised to a easy win (3 Mile) at Billings. (teammate Christina Aragon was on recruiting trip). Last week again at Billings she destroyed the field seemingly unaffected by the 95+ degree heat that had the rest of the field firmly in its grip. This past Saturday she completely left the field again and broke the Sheridan VA course record by over a minute running 17:41 (elevation 3143). One has to wonder what she could have laid down at Liberty Bell?
