Earlier this week Charlie Engle began his attempt to break the world record for running across America.  Today ultramarathon man Dean Karnazes is attempting to run on a treadmill for 48 hours to set a new world record.  He started running this morning on the Live with Regis and Kelly show in New York.  You can watch the live webcast of Dean running  and be sure to catch the show Thursday morning to see him break the record.

I hate running on the treadmill for any time beyond an hour, there is definitely a huge mental hurdle to overcome to withstand the monotony.  For Dean, this kind of mental toughness likely comes with disciplined endurance training.  Find endurance training tips from Dean himself in his book “50/50: Secrets I Learned Running 50 Marathons in 50 Days — and How You Too Can Achieve Super Endurance!“
