That's awesome, well done!
For a while I tested 1h and 2h after food to see how it would affect me as often I was not as high as I'd expect after some meals and I wanted to find out how far up the spike went.
Turns out sweet potato is good for before training, same for bananas. I got away with a small handful of wholegrain pasta and vegetables before training too and a small amount of oats in my morning yoghurt was ok too - that was when I was active and training 6x a week but with Corona cancelling training, I reduced my carbs further as I can't handle them as well.
Had to up my basal insulin this week too and sort of got an ok level again of maintain good control.
I found especially at the start it's all about testing and learning. I used MySugr app to keep track and look at trends until I had an idea on what worked for me.
