For London 2012 gold medallist Dani Rowe, however, retirement means walking with the aid of crutches and a surgical boot.
The 28-year-old said a bit of gentle exercise ended in a visit to the doctor.
“Not exactly the best start to my retirement from professional cycling but at least I now know a career in professional running is not my future!
“Stress fracture of my calcaneus (heel bone) so the next six weeks will be spent in this glorious boot!”
The Briton, who won team pursuit gold at the London 2012 Olympics and three consecutive World Championship titles in the event between 2011 and 2013, said retirement was “the end of one chapter in my career, and the start of a new one”.
