I decided shortly after my original post that I would like to subscribe to Zwift (which is an online game for at home cyclists).
If you don't mind, I will turn this thread into my Zwift journey blog.
First day of Zwift today.
I bought a Zwift Hub smart trainer. Setup was easy, I did not manage to connect it to my phone for whatever reason, but I easily connected it to my laptop, which as it turns out is even better.
You can do 8+ different things on Zwift (race, workout, follow a training plan, free ride, group ride, follow a pace partner (ro-)bot, ride "erg" mode or what I did: "ride routes"). I decided that I would like to ride all of the routes in the game. So I did ride 6 different routes (these are official routes) 2 of them are basically the same route as 2 others just backwards, but anyway I did 52.4 km (or 32.5 miles) in total. which was enough to earn me 2 levels (I am level 3 now). According to Zwift I have burned 950 kcal, and rode for almost 2 hours. I think that is a nice start.
Plan for tomorrow:
Length: 29.5 km (18.3 miles)
Elevation: 682 m
I am trying to follow this plan:
Ride all 80 open routes using our progressive 60-day schedule.
but I still need to understand the nuances.
My current estimated FTP is 137
(I didn't do any kind of tests) and my Watt/kg is usually around 1.8.
A very good start, I am very happy.
Zwift is fun, I highly recommend it.
