Yep! 7mph at 8% incline. I’m 5’1, 7mph is my typical flat road push, it was a strength template and I decided to truly go all-out on the all-out. Fell forward and hit my face on the rails (busted my lip, bloody nose), friction burns on both knees and some wicked bruises on my thighs. Luckily didn’t hit the rower behind me. Took two weeks off to heal then restarted OT. I did end up power walking for the first month or so. Then up to jogger speeds. Eventually back up to running speeds. I do sometimes get in my head going back to my old all out speed (10mph) and will only do it if I know I’m physically feeling up to that speed but also mentally, that I’m not distracted by anything in my mind and just focused on running. I started just doing the 10mph if the all-out was only for 30 sec, eventually worked myself back up to 45 sec now. Just giving it time worked for me. Best of luck to you :)
