You've done a great job, Catrin. Just remember that you need to find your "balance," so you don't get hurt or sick. As someone whose body responds quite nicely to over training , I have learned the hard way. Thankfully, I learned this lesson in my thirties, so while I have had some instances of making a situation worse by my own stupidity in the past few years, mostly, I feel fine when I have to cut back or stop an activity. Like running; I really like it, but it does not like me.
I was thinking that I didn't do a 50 mile ride until I had been riding 4 years! Sure, I did lots of 30-40 mile hilly rides, but you really did ramp up quickly. And remember, what works for one person, is not necessarily true for another. I cannot do an intensive workout 5-6 days a week. While I do something generally 6 days a week, at least 2 of those days it's yoga or core work, or walking/hiking/light weight lifting. I quit my gym 1.5 years ago and do this all at home. And my weight and body fat has remained stable or even a bit lower. So, listen to your body. Half of fitness is the mental aspect.
