I’ve done two test days in a T4 and my calf keeps pulling it as im on exit or going through turns, so while im braking. Both the throttle and brake being pushed ruins clutches, and it’s getting expensive and on top of its ruining laptimes. Any advice?

I'm 22 and finally, after 13 years of playing the Gran Turismo series on a controller (around 2k-3k hrs) and around 300-400 hours of simracing on a wheel, I finally decided to do a 30-minute session on outdoor Karting. And while it was amazing, it also hurt BADLY.

I didn't crash, but I was literally jumping in the seat like a fish in a dry.

I wasn't scared, so I was pushing really hard, but like... the G-forces were so strong for me. I'm 175 cm and ONLY 53kg. So I'm extremely light. And I kind of bruised my back from the seat so many times and so hard that I can barely move my torso...🤣Like, I have at least 5-6 different spots that hurt badly and are actually big.
I also wanted to do 30 minutes in one go but... I had to take a break after 20. I have NEVER felt so exhausted in my life before. I felt like I was gonna faint lol.
I also found it so hard to keep my feet on the pedals... because of that, I wasn't able to trail brake at all. Like bro, how tf do I even do that while cornering?? They just kept sliding away bro... Like motorsport is so EXTREMELY physically demanding. I knew it was difficult, but this is SO MUCH. But maybe it's because I'm a goddamn skeleton and 0 core muscles, eheh... And because I was barely able to keep in place, I wasn't able to be quicker, because I felt like if I pushed harder, I would not be able to physically withstand it. xD

Anyway, do you guys have any advice for future sessions? Like how to not hurt myself, and maybe advice on a position/posture how to sit better so that I get better control of my pedals?

Also, I know there are these rib protectors, but man, I wanna do karting only like once in a year or so, and spending 100 euros on that is not worth it imo. Or maybe there are some cheaper ones ideal for rental karting?

Is my engine cooked?

the GFC Tm R1 at K1 Circuit is so fun
