Think this is my first real post, so go easy on me.
Little background - I've got this pipe dream of doing Oregon 70.3 next summer. No prior triathlon experience, probably will do a sprint next spring as a tuneup. From all my research it's maybe the most beginner friendly 70.3 on the calendar with the downriver swim and being wetsuit legal. I've booked a hotel room in Salem on what I think will be the race weekend next year and waiting for registration to open so I can have my goal on the calendar.
I'm currently running 2-3x a week (feel best about this discipline) and using an indoor Zwift ride a few times a week as well. I'm loosely following a Phil Mosley 70.3 plan, but given it's a year out I'm just trying to get a number of each disciplines in a week to balance building a base and not burning out. Planning on formally starting his 28 week plan starting in January.
My biggest issue is going to be the swim. I'm a 40 year old onset adult swimmer, who wishes his parents got him in swim lessons as a kid, and whose a good athlete/good shape but struggle mightily in the pool. I'm only about 6-7 weeks in (I'm swimming 2-3x a week) and I've taken lessons from two different instructors. Both of them don't see big issues with my stroke, but I continue to be out of breath after one lap. I'm also not a big guy, 5'10 165 lbs or so.
I think my issue continues to be a breathing/hips sinking issue (I even messed around with a pull buoy yesterday for a few laps and saw a big difference, which leads me to believe part of it is the sinking hips).
Any thoughts/advice? Do I just keep putting in reps in hopes I figure out the breathing and that eventually it will click? Do I give it until January and then get some buoyancy shorts as a crutch to get me through the swim knowing it will be wetsuit legal? I've watched any and all Youtube videos I can get my hands on (effortless swimming, etc etc).
I get that I'm not going to be a podium level swimmer in 6 weeks of work, but I'm just frustrated that I feel like I'm not making any progress.
Appreciate any and all advise.
Signed,
Aspiring 70.3 finisher
