I am a relatively new rider who aimed until now to do long rides of 100-120 km 2-3 times a week. Thankfull I live by the shore so my training was almost completely flat.
I am 1.92 with 92 kilos and I intend to do a 200km brevet with 3500m of climbs. This will be my second brevet. The first was a rather flat 200km one.
My question is that I have 2 months to train. I discovered that I love climbs and I do one climbing session a week now. However what would be the most efficient way to conquer the 3500m climbs in 2 months? Should I do more flats so I lose 4-5 kilos and have it easier to climb or do more climbs? In my climbs at my current physical I am always over 75% of heart rate. I am getting stronger but still I am far from fat burning zone. In 2 months what is the most efficient path to follow ... or climb?
