At 10.56 cents per EQM, this doesn't remotely qualify as a Mileage Run. Even for an AS MVPG75K with 125% Elite bonus miles the RDM is 3.25 cpm. That is 62.5% higher than you can purchase the miles for with current promtions.
Unless this is an itinerary you have a need to fly, it doesn't make sense to fly it for AS accrual.
