An early morning work out before a day of crucial meetings behind closed doors.
U.S. Treasury Secretary Timothy Geithner is in Europe again - to pressure leaders into assuring markets they have a plan to stem the euro zone crisis.
He's meeting European Central Bank President Mario Draghi in Frankfurt - where he may call for the Bank to play a greater role in supporting debt laden countries.
He's also meeting Germany's finance minister in Berlin before heading off to France and Italy to talk to leaders ahead of a crucial European summit on Friday.
It's his fourth visit to Europe since September - and highlights the United States' increasing nervousness about the threat posed by the euro zone to the health of the U.S. economy.
