Hi, i'm 22 and i've never been running for any competition. I'm 180cm and i weigh 76kg. I'm an active guy who walks a lot and plays a lot of sports for fun. A few weeks ago a colleague who runs constantly asked me to go for a run to catch up with things. We did a 5k and i cruised it in 26 mins, i was surprised tbh. Last week we tried again a 10k and i had something left in the tank but still got 54 mins. Now i managed to get a spot for the Berlin Marathon somehow and i have 11 weeks of training left. I went to my local running club and the coach said that he signs me up professionally if i lose at least 5-10kg and i get under 4h in Berlin. Today i'll do a 13k run. Any thoughts on my chances for Berlin? Am i gifted for running? Thanks.
