Hi!

So as a fairly new Zwifter I just discovered how I can get the bike with the neon-light pimped wheels (Tron Bike) - its just to climb some hills. So far I have been doing mostly “flat” tracks, and I have got a feeling that on my spinbike with Power pedals I do about 30 km/h on flat tracks in Zwift. So today I had a couple of hours and saw this French mountain - only 20 km, but 1500 m/high… So I thought optimisticly “20 km… it should be possible in a couple of hours” - but how wrong I was!

During the ride I started to think and calculate - if its 9%+++ hill upwards, I only have 4-6 km/h, and then 20 km takes 3-4 hours… which is probably right with the watt input, so here is the question:

If I keep my flat 30 km/h “speed/watt/cadence - input” the whole way and don’t adjust the resistance on the spinbike - how much “longer” is the ride if there is a mountain track on 1000 or 1500 meter? Today 1,5 hr would normally give 50 km +, but I only managed about 12 km up the mountain and the last 8 kilometers I have to try again next time… So how do you calculate the time you will use if there is a mountain compared to a flat route? I can’t be the only one who has met the wall on a mountain… And is there a chance to countiniue on the same path from where I stopped next time?

(I hope this was understandable😊)
