Mo Farah will bid to become Britain's greatest track and field athlete as he goes for a second gold of London 2012.
Victory for the 29-year-old in the 5,000m, seven days after he set the Olympic Stadium alight by winning the 10,000m, would top a golden Games for Team GB.
Britain's best medal haul for 104 years was boosted even further today after a canoeist dubbed the "Usain Bolt of the water" won gold, the team's 26th.
Ed McKeever stormed to victory in the 200m kayak sprint getting Team GB off to a glorious start on the last full day of Olympic competition.
And just over an hour later on the water, Britain picked up another medal as the two-man crew of Liam Heath and Jon Schofield took a kayaking sprint bronze.
There are further medal prospects as Luke Campbell goes for boxing gold and Tom Daley dives for a medal in the Aquatic Centre.
A win for Farah would cement his position among Britain's best, according to Games chief Lord Coe.
Asked whether Farah could achieve the double, the Locog chairman said: "Yes he can - a lot will depend on how much he really wants it."
He added: "But if he thinks he can go down indelibly in British track and field as probably the greatest athlete we've produced, then yes. The question is, is he hungry?
"It would be hard to argue against a guy winning the 5,000m and 10,000m at an Olympic level."
