How good of a swimmer am I?

I've been lifting weights + running for a few years and have been swimming on and off for a couple of years. Last season I ramped up my swimming slightly to maybe 2000 meters 3 times per week. I'm gonna try a swimrun in about a month and have tried to increase my swimming to 4 times per week during the summer. I can do a 5k run in 20 mins if I max it so I think the running is fine but I don't know about my swimming. Best 100 meters time 1:20 (was few months ago, maybe I could increase it to 1:15 by now) I get really tired by it but I can do 3 intervalls of 100 meters at 1:30. With 1:30 rest. Longest crawl 1k (was really hard) 19 minutes I have tried to make a 400 meter swim in 7 minutes twice in the last week but had bad days both times and got like 7:30. I hope I am considered an intermediate swimmer at this but I'm not sure?
