They know the drills after their impressive debut at the water cube in Beijing, where Jason Dunford reached the finals of the 100m Butterfly while his younger brother David reached the semi-finals of the Freestyle.
“I am stronger and more experienced than I was two years ago,” David, 24, offered.
“I have a genuine belief that I can progress through the first round and into the finals in London.”
Jason the ‘seven-minute Olympic record holder’ is also very clear on his goals, and is enjoying a burst of form that could peak in London.
“I feel in much better shape and more confident going into my second Olympics. I am bringing with me more experience and coming off a 4th place finish at last year's world championship,” Jason, 26, said of his prospects of winning the country’s first Olympic Swimming medal.
“I can make it onto the medal stand!”
It is not only the confidence levels that are high the pre-requisite conditioning is all there.
Weeks of training at the ADN swim project in Italy, High Altitude endurance training at the in southern Spain for Jason, topped up by a final round of preparations in Bristol where part of the Kenyan Olympics team set camp for two weeks, has got the brothers in the right shape and frame for an incomparable experience at the Olympics Park Aquatic centre when the programme begins in four days time.
The Multiple African champions have also had a chance to test themselves against some of the swimmers they will be facing in London in top level competitions in Paris, Milan with some notable results.
Jason followed up his Orca Cup win in Slovakia in June with another imposing Paris Open title in early July, as he tapped the wall first in 52.55 seconds, his season best.
“I am really happy with the progress. I had also won the same event (100m fly) in Milan some days earlier,” Jason told sportsnewsarena.com from Bristol before they moved to the Olympic village monday.
Besides the European training camps, David, the Pan-African 100m freestyle champion, had a chance to go even faster in his speciality event, the 50m freestyle, from his yearlong training in his base in the US coupled with practice events against the Russian sprinters.
“In the Paris Open I made the final in a very fast 50m freestyle field and recorded a Season Best time that sets me up very well for the Games,” David explained of his 22.80 timing.
The self confessed water-rats who besides swimming are ardent surfers will each be competing in their speciality event unlike in Beijing where Jason tried out the 100m freestyle.
