Chain coming off over the front of the pedals

Took the bike out for a ride today and the chain keeps coming off at the front when changing up onto the big ring. It goes over the top and onto the pedal arm, meaning I have to quickly change down to get it back on.
Can someone advise on what part I need to adjust? I've got an 80 mile ride next week and as it came off around 12 times today, I could do without it

Cable tension too high and/or high limit screw needs adjusting.

Thanks very much, a lot better than the videos I had found. Made some adjustments, as it seemed quite out, had a quick spin and so far so good.
