Thanks to everyone who took the time to reply to my post on FOOD GLORIOUS FOOD.
This morning I decided to start my investigation. I soaked some porridge oats overnight so cooked those up this morning. I had a ramekin full of porridge with half a sliced banana and a cup of tea. Waited an hour then off I went to do my Magic 10 week 4 50 minute run. I decided that I would take it slow - after all I'm doing the time not distance version. Well, it was different! The toxic 10 definitely didn't feel as toxic and I felt more 'comfortable'. The second half of my run WAS hard but I didn't feel drained of energy like I had before. I finished the run and have had time to think that actually I did feel much better/even slightly good about my run. I felt I was running with intention and that my pace was quite strong. I was still very happy to stop though! Porridge & banana gets my vote although I'm going to continue experimenting. At least now I know what it CAN feel like so I can now compare and make an informed decision.
Note to self: Switch Mapmyrun over to kilometres not miles - to save great confusion.
Why do all these apps differ so greatly on time/pace/calories? - On MapmyRun my time was definitely 50 minutes! 🥵
