World triathlon champion Tim Don is confident he will be able to overturn a ban and compete at the 2008 Olympics.
Don celebrates his World Triathlon victory in Lausanne last month
Don, 28, was banned for three months for missing three out-of-competition drug tests in an 18-month period.
British Olympic Association rules state that Don should be suspended from the Olympics, but he could be reinstated if there are mitigating circumstances.
Don, who did not miss the tests intentionally, said: "I'll be appealing against the Olympic suspension, 100%."
The Englishman has passed nine tests on separate occasions this year, but fell foul of a new system whereby athletes must update an online database saying where they will be available for testing for one hour per day at least five days a week.
If they are not where they say they will be when a doping control officer arrives, the incident is reported as a missed test, three of which add up to an anti-doping rule violation.
I plan to educate young triathletes
Don is not challenging his punishment for breaking this rule.
But he hopes to use the example of Olympic 4x100m gold medallist Mark Lewis-Francis in order to make Beijing.
Lewis-Francis was banned following his positive test for cannabis after winning 60m silver at last year's world indoors.
But he is now allowed to compete in future Olympics after a successful appeal to the BOA.
"I will not be doing it immediately but following a set procedure. It's relieving to know that others in the past have appealed and been allowed to compete again for their country.
"The British Triathlon Association have been very supportive, and the independent panel stressed that I didn't deliberately miss the tests."
And Don is now determined to inform other athletes about the new system in a bid to prevent them from making the same mistakes.
"I plan to educate young triathletes, particularly those who have won the right to be fast-tracked to World and Olympic level," added Don.
"I'm meeting up with the national under-23 squad and I'll be emphasising they must get to grips and understand the importance of the new system."
Commonwealth Games 400m gold medallist Christine Ohuruogu has also been banned for missing three out-of-competition tests in 18 months, but has been suspended for one year.
She appealed to the Court of Arbitration for Sport last week although she has not yet lodged an appeal with the BOA.
