Hey there, I started swimming two years ago, I was very active in the summer of 2017 but then as it got colder I went less. In 2018 I didn't swim nearly as much, but still a bit, and now in 2019 I'm swimming even more than in 2017 (been at it everyday for almost a month) and I swim AT LEAST 1 kilometer and up to 3 kilometers. I usually swim 2 km.
Now the problem I have, I'm a really slow swimmer. Even if I try to swim as fast as I can (which sometimes results in stomach cramps and I get really out of breath) I just take so long. Now I'm not 100% certain how each kilometer takes me, but I think it's roughly 30-40 minutes.
I'm not really leisurely swimming (or that's what I feel like, maybe I am swimming at a turtle's pace), I do breaststroke and freestyle with 5 lap intervals. The pool I swim in is 25 meter long, so one kilometer is 40 laps. I am usually faster at the start but then I gradually slow down because of fatigue but I always try to keep the same pace.
I take over two hours usually if I decide to go for 3 kilometers. I've only recently started doing 3 kilometers, I have been thinking if I should start doing 4 but honestly 3 kilometers takes so much out of me and I'm really exhausted and hungry for the rest of the day.
I've been reading on tips and tricks with swimming and I've noticed that a lot of people say they can finish 2 kilometers in less than 40 minutes. I know that it's probably not helpful to compare myself with other people, but it bothers me and it makes me feel like I'm not putting in enough effort, although I'm always tired afterwards.
If it matters, I am 22, female, 170 cm, and currently 68 kg. I eat roughly 1250 - 1500 calories a day and I eat half of my exercise calories back, although I have been having some problems with binge eating lately which I am trying to fix. It actually kind of feels like the lighter I get, the less energy I have when I swim. I was 95 kilos when I first started.
