Britain's Liam Heath and Jon Schofield won bronze in the men's kayak K2 200m final as Russia's Yury Postrigay and Alexander Dyachenko took gold.
European champions Heath and Schofield were beaten into second by Postrigay and Dyachenko in the heats and semi-finals after poor starts.
British duo pleased with bronze
Despite their best getaway of the regatta, the Britons could not match Russia and were pipped by Belarus.
It was Britain's second medal of the day after
Ed McKeever won K1 gold.
Heath told BBC Sport: "That was a really long race. With a headwind like that, especially when you're going at that speed, it's really tough but I'm so pleased."
Schofield added: "That was a long race and I didn't think we were going to make it to the line. The last few days have been horrible. We weren't happy with our heat and we were worried. But that start was amazing and we just about held on to get a medal."
After a barren week for Britain in the canoe sprint events, McKeever delivered on his nickname of the "Usain Bolt of the water" with a dominant paddle to victory in the men's K1 single 200m on Friday.
An hour later, Heath and Schofield, who won silver at the World Championships last year, took to Dorney Lake hoping to repeat the trick.
Cheered on by a capacity crowd, which included Prime Minister David Cameron, the British pair began well and took an early lead.
But the Russians found an extra gear in the middle 100m, storming into a lead of almost a length with 50m to go, before easing off.
Britain were in second, but the fast-finishing Belarus crew of Raman Piatrushenka and Vadzim Makhneu stole silver on the line.
