你覺得自己夠強壯嗎？參加下面一項活動就是最好的檢驗方式。發展迅猛的冒險挑戰領域已經有許多知名的活動，比如斯巴達比賽（Spartan Race）和勇士沖刺（Warrior Dash）等，而迪恩在哈佛商學院（HBS）時與利文斯頓一同設計的“泥巴硬漢”（Mudder）無疑其中最具有知名度的一項，而這要得益于有效的品牌建設，以及與大牌贊助商的合作，比如墨西哥啤酒品牌Dos Equis（許多選手完成比賽后都會暢飲一杯啤酒）、Degree和美國體育裝備品牌Under Armour。隨著活動數量（今年有53項，在五個國家舉辦）和參賽人數（2012年參與者超過了460,000人，給公司帶來7,500萬美元收入）越來越多，很明顯，這兩個年輕人和他們的公司充滿了活力。——丹尼爾?羅伯茨??

Will Dean & Guy Livingstone

? Age: 32, 32

? Title: Co-founders

Think you're tough? Nowadays, running one of these events is the best way to prove it. In a fast-growing field of adventure-challenges with names like Spartan Race and Warrior Dash, the Mudder, which Livingstone and Dean came up with when Dean was at HBS, is arguably the best known thanks to effective brand-building and partnerships with big-name sponsors such as Dos Equis (many participants swig a beer after they finish the race), Degree, and Under Armour. With an ever-growing number of events (53 this year, in five countries) and participants (more than 460,000 in 2012, bringing some $75 million in revenue), it's clear these two guys and their business are showing some stamina.-Daniel Roberts??
