Hero Rush national obstacle course race series: Hero Rush is a new national race series debuting late April near Washington, D.C. The 5k to 7k courses include obstacles a firefighter would encounter on a call: “ … You’ll slide, climb, crawl, get wet, search for victims, drag and carry equipment, carry stretchers, race up stairs, fight your way through smoke and flames … and more!” says the event’s website. Registration fees cap at $84, but sign up early for a discounted price. Plus use the promo code MTimes to get 10 percent off the registration cost for any 2012 Hero Rush race. This is in addition to the $5 off that all active-duty and retired military members already receive.
