Text way too small

Just started zwift run on my new treadmill which has a tablet holder. Really like zwift run and the workouts/training plans are great. I have a 10.1 inch ipad but the text on the page is so small I can’t see it when running. In fact it’s making me feel a bit travel sick trying to read the screen when running. This is much worse than when on the bike in zwift as your head is still when on the bike. I know companion app is an option but that would involve looking down a lot because my phone will be on the tray on the treadmill. An option to fix this would be to have a heads up display at the bottom centre which has large text and rotates round the key info i.e. Workout progress then elapsed time, current speed etc.
