Participants undertook a pre-race 16-week training programme. Magnetic resonance imaging (MRI) of high-resolution 3.0 Tesla was used at each time point. Senior musculoskeletal radiologists assessed the lower lumbar spine condition.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Out of 28 participants, 21 completed both the training and the race and 7 neither completed the training nor started the marathon but not due to spine-related issues. At time point 1, disc degeneration was detected in 17\/28 (61%), most predominantly at spinal segments L4\u2013L5 and L5\u2013S1. No back pain\/other symptoms were reported. When compared to time point 2, there was no progression in the extent of disc degeneration, including intervertebral disc (IVD) height (<jats:italic>p<\/jats:italic>\u2009=\u20090.234), width (<jats:italic>p<\/jats:italic>\u2009=\u20090.359), and intervertebral distance (<jats:italic>p<\/jats:italic>\u2009=\u20090.641). There was a regression in 2 out of 8 (25%) participants who had pre-marathon sacroiliac joint bone marrow oedema, and a small increase in the size of a pre-marathon subchondral cyst in one participant, all asymptomatic.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Running 500 miles over 4\u00a0months plus a marathon for the first time had no adverse effects on the lumbar spine, even when early degenerative changes were present.
