Emerging evidence suggests peer support (i.e., assistance from individuals with lived experiences trained in behavior change techniques) may improve exercise adherence, yet its long\u2010term safety and feasibility remain unclear. This study evaluates the safety and feasibility of 12\u2009months of HIIT, with and without peer support, in cancer survivors. Breast, prostate, and colorectal cancer survivors completed 4\u2009weeks (12 sessions) of supervised HIIT before being randomized to receive weekly peer support from people with lived experience of a cancer diagnosis (HIIT+PS) or no peer support (HIIT\u2010Only) for 12\u2009months. Both groups were provided 12\u2009months of free access to local gymnasiums. Safety (adverse and severe adverse events) and feasibility (recruitment, attrition, attendance, adherence to intensity, duration, mode, peer supporter contact) were compared to a priori criteria. The a priori criterion was met for recruitment rate (38%) of study participants (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009137).

Both groups met the a priori criteria for safety (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20090 severe and\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20097 (0.5%) Grade 1\/2 adverse events), duration, and mode, but not attendance or intensity across the full 12\u2009months. A priori criterion for study attrition was met in the intervention group (23.7%) but not the HIIT\u2010Only group (30.8%). Twelve months of HIIT with and without peer support was safe with participants meeting the prescribed duration, and mode, but not attendance or intensity. Peer support provided weekly for four of every 5\u2009weeks appears insufficient to improve HIIT feasibility. Peer supporters preferred to provide contact via text messaging or face\u2010to\u2010face interactions. Future studies should explore strategies to improve long\u2010term HIIT frequency and intensity adherence.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Trial Registration:<\/jats:bold>\n                    Australian New Zealand Clinical Trial Registry 12\u2009618\u2009001\u2009855\u2009213.
