Writing in the Daily Express, Mr Farage said the May elections will be the next step in proving to voters and the political establishment that his party is a credible choice for government.
"It's clear that the country is crying out for change and voters continue to see Reform as a credible choice for government. May 1 is the next step to forward to making that happen," he added.
Thousands of supporters will descend on Birmingham on March 28 for the Reform rally. Mr Farage said more than 10,000 tickets I have been sold, adding he "hopes to see many Daily Express readers in attendance".
Putting the past fortnight's infighting behind him following MP Rupert Lowe's expulsion, Mr Farage points to polls from the past week showing that the drama has not dented Reform's support among voters. With the party averaging 26% in most polls, and frequently ahead of both Labour and the Tories, Mr Farage also says that his target in May is to win 200 seats in England for the first time.
Party chairman Zia Yusuf said: "Reform reconfirmed its remarkable polling this week, it's clear Britain wants real change."

An MRP poll based on 5,400 voters suggests the Conservatives will hold overall control of 10 councils, ahead of Reform's eight.
However Ms Rayner dealt a blow to the party's prospects with delays to elections in Thurrock, Norfolk, Suffolk and Essex where Reform is polling higher than the national average, because a local government shake-up is planned.
Had these elections gone ahead, Mr Farage could have been on course to win 12 councils compared to the Conservatives' 11 and the LibDems' eight.
Mr Farage's stated target of 200 gains in May is lower than that forecast by local election expert Lord Hayward, who said that despite cancelled elections in Reform strongholds the party has no excuse not to win over 400 seats.
Speaking last week, Lord Hayward said: "You can probably reasonably argue that ...
