The Ukombozi Rally brought together opposition leaders, among them Kalonzo Musyoka.
The day's activities began with a church service in Isinya attended by Gachagua before he proceeded with his convoy to Kitengela town, where he addressed residents.
At the church service, Gachagua called for respect for churches, urging politicians to conduct their political activities without interfering with the church.
He maintained that churches should remain respected spaces and should not be turned into battlegrounds for political confrontations.
The former Deputy President also urged Kenyans to maintain peace during the campaign season saying political competition should not be a reason for violence or hostility among citizens.
