Many members of the City of London community will run the Virgin London Marathon this weekend . But for those who have not spent the last week preparing for the event, a punt on the shares of the manufacturer of Lucozade, an official partner of the race, would have brought their own rewards.

Lucozade Sport is owned by pharmaceutical giant, Glaxo Smith Klein, whose share price has risen nearly 5% this week. GSK's shares also rose 3% in the week preceding last year's race where Lucozade was a sponsor.
