How to prepare for your first triathlon?
Training for a triathlon is easier than you think, even if you don’t seem to be in good enough shape for it yet. Yes, it’s true: without any specific fitness level, you can be ready for your first triathlon in just 12 weeks. And you don’t have to give up your life or drain your bank account to make it happen.
Here’s how to train for a triathlon from scratch:
Essential Equipment
You need some basic equipment for your first triathlon. This equipment doesn’t have to be expensive; in fact, you can even borrow gear from a triathlete friend.
For swimming: a swimsuit, goggles, and a swim cap (especially if you have long hair).
For the cycling portion: a bike suited to your riding comfort and in good working condition. It can be a road bike, mountain bike, or hybrid. You can rent a trial bike if possible, but you don’t need a real triathlon bike to get started.
For clothing: padded cycling shorts and a simple, close-fitting jersey, as comfortable as possible.
You can use flat pedals or clipless pedals (cycling shoes help but are not essential).
Plan to bring a water bottle for your longer bike rides.
For running: a good pair of running shoes. You don’t have to spend €200 to get an excellent pair of shoes, but you do need a pair designed for running that fits your feet.
Take Time to Prepare
If you haven’t been physically active for far too long, it’s a good idea to give yourself about 12 weeks to get in shape and minimize the risk of injury.
In 12 weeks, you can condition your tendons, ligaments, and endurance so you can get the most out of the race. If you can train five days a week, for a total of two and a half to four hours per week, you clearly have enough time to get in shape.
Weekday training sessions should only be 30 to 45 minutes, while weekends can be used to build endurance. During your longest training session, it’s best to keep the cycling portion to no more than one and a half to two hours.
Of your five weekly sessions, do swimming exercises during two of them.
Make sure that two combined training sessions are designed to build endurance and minimize the risk of injury.
Examples of combined workouts for the first week:
Combo Workout No. 1:
(Run 1 minute, walk 1 minute) x 5, then cycle for 30 minutes at an easy intensity. (Zone 1 to 2 for those using a heart-rate monitor.) You can even do this workout at the gym.
Combo Workout No. 2:
(Run 1 minute, walk 1 minute) x 7 or 8, then cycle for 30 minutes at an easy intensity
For the fifth and final workout of your first week, cycle for 45 minutes at an easy, conversational intensity.
From there, you can create your own plan with flexibility.
Workout No. 1: Swim 5 x 100 (20 sec Intermediate Recovery (RI)), easy to moderate (Zones 1 to 3)
Workout No. 2: Combo: run 25 minutes, Zones 1 to 2, cycle 20 minutes, Zones 1 to 3
Workout No. 3: Swim 5 x 100 (20 sec RI), easy to moderate (Zones 1 to 2)
Workout No. 4: Brick: cycle for 25 minutes, then transition into a 20-minute run at Zone 1 to 2 intensity. Include 30-second accelerations
Workout No. 5: Long 1H30 bike ride at Zone 1 to 2 intensity on a rolling course.
When you’re learning how to train for a triathlon, it’s tempting to keep adding more and more training volume, but your fitness will improve through a balance of less stress and more rest.
If you’re planning your own training program, make sure to include recovery days and reduced-volume rest weeks to allow your body to rebuild and become stronger.
With basic equipment in hand and a planned route mapped out, there’s nothing left to do but get started. There’s no better time than now, so go for it!
