For me (<--- probably the most important thing to note) I just get back to riding my bike.
No intervals. No riding in rubbish weather. No 'dragging' myself out of bed for an early morning spin. Ride for when as and as long as I like.
As what I love, more than racing, beating my times or other people's, is just being outside on my bike. Catching up with mates and enjoying everything around me (and a good cafe or two). Given the choice, I'd take a two weeks away with my bike as my version of a 'relaxing holiday'. Others would go to a resort
If you have a coach hopefully he'll be as understanding as mine. In fact, doing the above came from him. Only ever been in one massive 'low' with the bike, and doing the above fixed it.
Also lost no fitness. The first couple of interval sessions back hurt, but then was back to punching out good power numbers again. And, importantly, loving it.
YMMV, hopefully this helps.
