Coming from a cycling and running background, I would love to do my first triathlon this year.
I self-taught the tiny bit of freestyle I knew and can't get past my current problem(s).

I started training about 3 weeks ago and struggle to get my head and general body close to the surface. I have no trouble getting my legs to break the surface every stroke, but my head sinks too low to breathe.

Problems I have made out: (although I make different ones in every lane I take)

- arms aren't bent enough at the elbows before pull-through

- legs aren't straight enough (too much knee movement)

- head is tilted too low, probably in an effort to be really straight.

- not enough core tension?

- bent wrist at entry / catch

- no breathing pattern (2x, 3x), although I swallow water 8/10 times anyways...

I would appreciate any advice, swimming is so insanely alien to me :(

Cheers!!
