I've not been cycling for months. Diagnosed with prostate cancer in January hasn't helped and I'm not sure if my day/week long rides weren't a contributing factor. A family friend was also killed on his bike last year. My enthusiasm is almost nil at the moment.
Went through 4 weeks of radiotherapy last year (no op) and had to take a good few weeks off for the side-effects to ease, but eventually got back into it. What I notice now is how the hormone injections to kill the testosterone make it hard to push the effort levels. Restricted to the turbo now for other reasons, but I'm hoping to be back out on the road in a few weeks.
