Wondering if anyone has had the same issues or experience as me...
Back last April I ran the London Marathon. It was the hottest ever, and training had been completed at around 7 or 8 degrees, not the 28 of race day.
Around miles 18/19, I saw family and got a bit emotional, lump in the throat sort of thing, and around 200 metres after I set off again it became hard to breathe. I slowed and took some deep breaths and everything eventually seemed to ease off. Stopped at the next medical tent and they gave me some Lucozade, a pat on the back and I carried on. Another few times along the route I struggled to breathe so eased off and took some deep breaths each time. I managed to finish, and after around mile 24 wasn't having any further breathing issues. Seemingly no issues when I've run afterwards but granted nothing over 10 miles since.
I will add I'm not a small guy. 6 foot 5 and 19 stone so I appreciate weight may come into it somewhere but having not had issues previously I wondered if anyone else experienced the same?
I understand asking here is going to prompt suggestions to speak to a medical professional which I have already done (they seemed to gloss over my question and not seem too bothered which I suppose is positive!) but I have put my name forward to run for charity again in 2020. Nothing like this happened in training at all.
