text: 2012 for undisclosed reasons. Following its cancellation in 2005, the MDTA considered decreasing the annual frequency of the event, citing traffic, fiscal, manpower, and security concerns. The most recent event (held in 2006) cost over $350,000, and the cost estimate for 2012 was almost $400,000. In late 2011, a non-profit group, the Greater Washington Sports Alliance (GWSA), approached the MDTA Capital Committee to propose sponsoring the event, along with a concert at Sandy Point State Park, at no cost to the MDTA. While the Capital Committee unanimously recommended that the MDTA Board approve the proposal contingent upon an agreement between the GWSA and the MDTA, the 2012 event was ultimately cancelled.
  After increasingly consistent cancellations of the walking event, the MDTA, along with Queen Anne's County, contracted with an outside company to have a professional 10K race across the bridge, which has been labeled the "Across the Bay 10K". The inaugural event occurred November 9, 2014. The Race Director is Dave McGillivray, who has served in that capacity for the BAA Boston Marathon since 1988. The Across the Bay 10K has several charity beneficiaries, including bay research, bay restoration, and breast cancer research. The IRONMAN Foundation took over the race's organization in 2016. In 2019, the race was held virtually due to maintenance on the bridge.
