Eliud Kipchoge was 26 seconds from making history on May 6. Nike and Adidas have announced separate plans to attack the 2-hour marathon, with both introducing shoe lines linked to the effort. Wireless tech giant Vodafone last month said it was backing a third bid, hoping data gleaned from the quest will translate into wearable technology. (AP Photo/Luca Bruno, File)
