The Best Way To Train For A Sprint Duathlon (5/20/2.5km)

A sprint distance duathlon usually involves a 5km run, a 20-km bike and a 2.5-km run, although these distances can vary slightly. The best way to train for a sprint duathlon is by making regular cycling and running a part of your lifestyle. Plus, some strength training, if you have the additional time. 

Top Training Tips For A Sprint Duathlon (5/20/2.5km)

The challenge of training for a sprint duathlon is trying to fit your training around everything else in your life. A good place to start is by getting an expertly designed training plan. People who use training plans have been shown to be twice as likely to succeed in reaching their goals.

To improve at both disciplines simultaneously, you need to train two or three times per week for each one. Sprint duathlon workouts are typically 20 to 90 minutes in duration, depending on your fitness and aims.

Aim to cycle two or three times per week, or more if you’re experienced. One of your weekly rides should be focused on endurance, where you gradually build up to riding 60 to 90 minutes in training. This will help you develop enough stamina for a sprint duathlon, with a little to spare.

Another weekly ride should be more focused on speed, where you ride for 30 to 60 minutes, including easy and harder efforts. For example, 3 x 10 minutes at approximate 1-hour race pace, with two-minute recoveries (plus a warm up and warm down).  You should progress these rides over time, so your body keeps adapting to new stimulus.

You can either cycle outdoors in good weather, or indoors using a static bike or an indoor trainer. Many indoor trainers enable you to wirelessly link to interactive cycling software like Zwift. This means you can ride with real people in a virtual environment – which can make it more fun. The workouts in our training plans can be exported to platforms such as Zwift, TrainerRoad and Garmin. However, it’s sensible to do at least some of your training outside on the bike you intend to use during your duathlon. This ensures you’re used to the feel and handling of your race-day bike.

Aim to run two or three times per week, or more if you’re experienced. Be sensible about your speed and distances, to avoid injury. For example, start off by running 2 miles and increase your distance by 1 mile per month until you’re able to run at least four miles. Do most of your runs at chatting pace, even if it means you include some walking. This will help you steer clear of injuries. It’s also good to do some harder efforts but interspersed with plenty of easy stuff. Be patient with your running. Impatience leads to injuries, and consistency is your goal.

In the last six weeks of your training, include some runs straight after cycling. And a few cycles straight after a run. This will get you used to the “heavy legs” feeling you’ll experience on race day, when you switch from run to bike, and bike to run.

There are normally two 40-minute strength and conditioning sessions per week with our sprint duathlon plans. Not everyone can fit them in around their busy lives, on top of their running and cycling, but it’s good if you can. These workouts improve your strength and flexibility, which leads to more efficient movement patterns and fewer injuries.

Using A Sprint Duathlon (5/20/2.5km) Training Plan

Online training plans are for athletes who don’t feel the need for a personal coach, but who still want the structure and planning of an expertly-written training program. Research has shown that you are twice as likely to reach your goals if you train with a structured plan. 

For a beginner who has some recent background in fitness or sport, it will take around 12 weeks to get fit enough to complete a sprint duathlon. The sooner you start, the more time you will have to build up your fitness gradually. Fitness adaptations take weeks and months to occur, rather than days.

MORE THAN JUST A TRAINING PLAN

We use TrainingPeaks to deliver your plan – the world’s most popular endurance coaching platform. Free to use, TrainingPeaks is an online calendar that lets you record, track and analyze your training sessions. 

It has a host of great features allowing you to get as in-depth as you like, including the ability to export your workouts to your training devices (Garmin, TrainerRoad etc) and follow them in real time. 

TrainingPeaks enables us to set you in-depth training plans in a way that other formats cannot. Phil Mosley is a Certified Coach and one of the best-selling coaches on the platform.

We want to provide an affordable and effective training solution, including email coach support for any questions you may have.

As you can understand, some limits apply, like personalisation or analysis of your training, but for anything else relevant to your plan, we would love to help. You also have full access to our online help centre, with videos and articles to help you train effectively.

We have a huge range of plans that enables you to select one that best meets your goals, schedule and ability. If you’re not sure where to start, read on below for a quick overview.

What type?
Our Standard and Masters plans are designed to get you ready for your target event, while our Off-Season plans are designed to allow you to recover from a tough season whilst maintaining your well-earned fitness. Generally, Masters plans are designed for athletes over 40 years old, although plenty of younger athletes love them too. The workouts are just as tough as with our standard training plans, but with more scheduled recovery days. Some find it easy to carry on with a normal training load, while others need to change their approach to training.

What length?
For the best outcome, count back from your “A” target race date and simply choose a plan to fill that gap (you can still work in other, smaller races during your plan). Note that longer plans start easier and progress more gradually than shorter plans. The body responds best to constant, gradual progression with regular recovery periods, and that’s exactly what our plans are designed to give you!

What level?
Choosing the correct level will help you get the most out of your plan. Generally, if you’ve never done this event before or currently train up to a few times per week, you might consider a Beginner plan. Alternatively, if you’ve done this event many times before or currently train 5+ times a week, you might consider an Advanced plan.

But don’t worry too much – we also let you swap the level for free within 14 days of purchase, if you find it too easy/hard!

Visit the MyProCoach Help Center for further guidance and to contact our Certified coaching team.

Certainly! Our training plans allow you to easily swap a few days around each week to suit your availability. Or you can swap out a session, to attend a similar group workout instead. That’s fine. If you opt for TrainingPeaks Premium (from $9.92 per month) you can even drag & drop your workouts onto different days. We give a few recommendations on how to best do this in our help centre.

And you can also train for multiple events! Our training plans guide you up to your target “A” race, but it’s also good to include some “B or C” races along the way. Our help centre goes through the exact steps you should take to enable you to get full benefit, without detracting from your key focus

FEEDBACK FROM MY DUATHLON CLIENTS

I just finished the advanced 12 week duathlon plan and ended with 3rd overall, 1st in age group and a PB on my bike. Thank you so much for a great training plan. Everyone should be following them!

I just thought I'd let you know that using your schedule, I managed to qualify for the World Duathlon Champs in Canada in Aug. To say I was pleased would be an understatement! wic
Robert Wickham - May 2017

I had a great race on Sunday, qualifying in 3rd and took 2 mins off my bike and dipped under the hour thanks to your training plan - I'll use another in the future. Thanks.

Planning Your Off-Season

You can start our Off-Season (Fitness Maintenance) plans anytime you like.

They’re designed to help you maintain a good level of fitness when you’re not specifically targeting an event, such as, during the off-season, or anytime you’re taking a break from racing.

Planning For Your Event

For the best outcome, input the date for your “A” target race and the tool will default to a plan that will fill that gap nicely. If you want, you can then adjust the plan length to start it on a different day.

Note that you can still work in other, smaller races during your plan too!

Unlimited Athlete Price Rise - Dec 1st 2021

As mentioned a couple of weeks ago, after 2 hugely successful years of our Unlimited Athlete subscription with over 1300 active members, we’ve decided to increase our prices for the first time on December 1st.

The feedback has been outstanding (rated 5.0 from 100’s of testimonials), and recently we’ve also added further personal coach time… For example, our coaches now check your personalised training zones are set up correctly, and also keep you accountable by getting in touch if you haven’t logged any training for 2 weeks.

So, to maintain this great customer service and to support our coaches, on Dec 1st we’re increasing both price options by $5 per month, or by $4 per month if you pay annually (but for all existing Unlimited Athletes, to give a fair warning, renewals will not increase in price until Feb 1st, 2022).

Lock-In Prices, Plus an Extra $20-Off!

For Black Friday, we are also giving a bonus $20 off any new annual subscription! Our annual prices are going up by $4 per month, or $48 per year. This means if you sign up this week with our bonus $20 off, you’ll be saving $68 compared to our future annual pricing.

Which comes down to as little as $3.55 per week for unlimited training plans and ongoing certified coach support. We can’t thank everyone enough for all your support!

The longer plans start easier and progress more gradually. This has a bearing on the difficulty level you choose. For example, a 12-week plan starts off at a higher level than a 36-week plan because with 12 weeks left there’s not as much opportunity to build up slowly.
