doing dual training for the first time advice please

Welcome to the craziness, Jude!

I typically will swim in the morning and do a ride or run in the evening or afternoon during a training plan during the week.

On the weekends, I typically do a long ride on Saturday morning followed by a short run off the bike (this is called a brick session). When training for a 70.3 I may ride 2:30 hours followed by a 20 minute run.

I would try and look up a program and see what it looks like for 6 weeks out from an Olympic distance. I think beginner triathlete has some Olympic distance plans you can consult.

Good luck!

I don't think there is a need to do all 3 sports in one day.

For brick workout (bike+run), I was given an advice here, I believe by Karen, aka HotRunner, to run approx. 20-30 minutes after the bike. And this should be enough to train the legs on how they will feel after the bike.

Did I hear my name??

In general, yes, unless you are training for a half full Ironman (and even then, much of the time), you would want to limit "brick" workouts (where you bike, then run immediately after) to 1-2X a week, and the run can be as short as 15 minutes, no longer than 30. The goal is really just to get used to the feeling of running after being on the bike. With practice, most people can get into a comfortable running rhythm a bit faster than if they had not practiced that transition.

For most of your workouts, you want to focus on gradually building endurance with running, biking, and swimming. Most people rarely do all three sports in one day in training, and on days that you might do two different sports, there is no need to do the workouts back to back unless your schedule requires that. When I have double workouts, typically I do one in the morning before work, and one later, between work and dinner. I'm guessing that's probably true for most people who are working or have kids to get off to school, etc.

Yup, this is exactly what you said few years ago on this subject
