Master's Edition: Karen and Manny Olivo -- the ultrarunning power couple

There's an old saw in ultrarunning that you shouldn't crew or pace your significant other. Too much potential drama, they say. Well, Karen and Manny Olivo have proven that to be wrong. This couple, married three years, support each other through 100Ks, 100-milers and more. Sometimes in the 125-degree heat of Death Valley in July. In a few weeks, Manny will take on that specific challenge at the Badwater 135, with Karen crewing for him. From there, they both will be doing the Berlin marathon in September and possibly trying to get into the Western States 100. YouTube link to their channel
