Waide captained Donegal in the final and scored three points as the team won their first Ulster minor title in 10 years at Croke Park in 2006.[3] In 2009, he made substitute appearances for the Donegal senior team in the second halves of their championship victory over Galway at Markievicz Park and their defeat to Cork at Croke Park.[4][5] He was injured in 2012.[6]
He then played for his club in the final of the 2019 Donegal Senior Football Championship (the first two games of three). After the first two games finished level, his club won the third game and, with that, the title.[10]
He also played for his club in the final of the 2023 Donegal Senior Football Championship, appearing as a substitute in this one. His club won.[14][15][16] This was his nineteenth season with his club, and though he was not often starting games, because of injury, he would often appear later on.[2] Ahead of the 2023 final, Waide (alongside Marty Boyle, Stephen McGrath, Anthony Thompson and Leo McLoone) was recognised for making a 100th club championship appearance.[17]
