if the muscles adapt quickly, the cardiovascular system works all the time with overload. Add to this the fact that beginners rarely bother buying a heart rate monitor and skate on sensations. The problem is compounded by the fact that cycling, unlike other sports hobbies, takes a much longer time. 100 km, which is so nice to roll on a day off, take four to five hours of clean traffic. Five hours your body works with overload, the pulse is driven into an unusual training zone (you want to improve the average speed a little).

Your muscles can adapt quickly, and your cardiovascular system can work on overdrive for hours without stopping. Unlike the advanced athlete, beginners don't typcally bother buying a heart rate monitor and can afford to skate on sensations (don't worry about every little thing your body is telling you).
