Age of Conan is going to do precisely that by running a race. Director Joel Bylos discusses the upcoming Great Hyborian Race in his director's letter for August, an event designed to promote PvP as well as give everyone a chance to see the game through new eyes. New players and old will have a chance for glory, fame, and fantastic prizes.
How will it work? After the server merge (which has been delayed slightly by moving the game's offices), a new Blood and Glory ruleset server will be started specifically for the race. Players will have sharply limited use of XP potions, no use of offline levels, and a simple goal of reaching level 80 as fast as possible. Prizes will be given to players who reach the top first and who gain the most PvP experience. The letter also discusses upcoming unchained dungeons and upcoming unchained PvP, so even if you don't want to race you'll have something to explore.
