cycling on mostly flat roads is not as intense as running to be fair, what I like in cycling is going uphill out of the saddle, I used to do hills repeatedly like that, totalling a few vertical kilometers without refueling nor drinking, that gave great sensations It's always a great idea to do regular cycling no matter the elevation as it's a great "compacting machine" for digestion
