What Is Hybrid Endurance Coaching? Strength and Endurance in One Plan

What Is Hybrid Training?

Hybrid training means lifting and endurance work in the same programme. A hybrid athlete does both on purpose. Researchers call it concurrent training, which is the term to search for if you want to read the studies.

A lot of what’s written about it comes from the lifting side: someone who loves the gym adds some conditioning, and the programme gets built around the barbell. I come at it from the endurance side. In my plans the endurance goal sets the direction and the strength work is there to support it.

The idea is less exotic than it sounds. The NHS recommends that adults do at least 150 minutes of moderate activity or 75 minutes of vigorous activity a week, plus strengthening exercises for all the major muscle groups on at least two days. That’s hybrid training at its mildest. A hybrid athlete just takes both halves more seriously.

I’ve always believed there’s more to endurance training than building a bigger engine. Your muscles, joints and bones still have to cope with the repeated demands of running for hours, which is why strength training is such an important part of how I train and coach. Strength work also gives your bones the loading that helps maintain and improve their strength, so the whole body is better prepared for endurance.

Hybrid Training, a Hybrid Plan and a Hybrid Coach

These three get lumped together, but they’re different things. Hybrid training is the style: strength and endurance work in one block. A hybrid plan is a set of sessions that does it, and you can buy one off the shelf. A hybrid coach is a person who writes the plan for you, watches how you respond and changes it.

The classic mistake is stacking two full programmes on top of each other: a complete running plan, a complete gym split and a rest day if there’s time. It looks impressive on a spreadsheet. By Wednesday you’re too tired to do either properly, and your sleep and your long run are the first things to suffer.

Sorting that out is most of a coach’s job. Each phase needs one priority. Something else has to be turned down, and the whole thing has to move when the week doesn’t go to plan. A plan written in January can’t know you’ll have a rotten fortnight at work in March. A coach you speak to every week can.

Does Lifting Get in the Way of Running?

Mostly, no. It’s the first thing most runners and triathletes want to know, and it’s a fair worry. The idea is that the two kinds of training pull against each other, so each one blunts the gains from the other. That’s the interference effect, and it has been studied a lot.

A good place to start is a 2022 meta-analysis in Sports Medicine by Schumann and colleagues. It pooled 43 studies covering 1,090 healthy adults and compared people who did both types of training with people who only lifted. Muscle size and maximal strength came out about the same in both groups. The one thing that dipped was explosive strength, the ability to produce force quickly, which matters more for jumping and sprinting than for a half marathon. That dip was bigger when strength and endurance work were done in the same session than when they were at least three hours apart. And the picture didn’t change significantly with the type of endurance work (running or cycling), how often people trained, their training status or their age (over or under 40).

The other half of the question is whether lifting helps the endurance side. A 2024 review in Sports Medicine by Llanos-Lagos and colleagues looked at 31 studies and 652 middle- and long-distance runners. Heavy lifting, meaning loads of 80 per cent of your one-rep max or more, or seven reps or fewer, improved running economy, which is how much energy it costs you to hold a given pace. The benefit was bigger at faster speeds. Lighter loads and isometric holds showed no significant improvement, although only three studies tested each. Most of the heavy-lifting programmes ran for 6 to 14 weeks at two to four sessions a week. The evidence was rated moderate to low certainty, so I wouldn’t call it settled.

For triathletes there’s a smaller study worth knowing about. In a 26-week trial published in 2021 in the International Journal of Sports Physiology and Performance, 25 long-distance triathletes were split into two groups. Fourteen added strength training and eleven stuck to endurance training alone. The strength group became more economical on the bike over the first 14 weeks and on the run between weeks 14 and 26, and their body mass didn’t change. The endurance-only group showed no significant improvement in any of the economy measures. It’s a small study, so I hold it loosely, but it’s a fair answer to the worry about bulking up.

Interference does happen, though. Greg Nuckols, writing about it for Stronger by Science, points to the situations where it’s more likely: very high endurance volume or intensity, poor sleep, high stress, a big calorie deficit, or ramping up too fast. Most of those can be planned around, as long as somebody is paying attention.

What a Hybrid Week Looks Like

Here’s one example, for someone training for a half marathon with five days a week to give it. Yours would shift around work, family, injuries and how far away the race is.

I’ve put the hard running and the heavy lifting on the same day, with a gap of three hours or more, so that Wednesday and Friday can be properly easy. The lifting is heavy and low in reps, which is the kind the runners’ review found useful.

For a triathlete the same idea holds, with a swim and a ride fitted around the run. There’s less room in the week, so every strength session has to earn its place.

When I was training for the Lakesman and Manchester to Liverpool, endurance made up a big part of my week, but strength was always part of the bigger picture. A typical week had three or four endurance sessions, including an easy session, some higher-intensity work and a longer weekend session, alongside two strength sessions focused on building a strong, resilient body. Looking back, I’d be smarter with my training now. I’d put more emphasis on quality, recovery and well-placed strength work, rather than thinking that more volume automatically meant better preparation.

Who Hybrid Coaching Suits, and Who It Doesn’t

It suits people who do some endurance training already, or want to, and who’d like to get stronger as well instead of treating the gym as an afterthought. A race in the diary helps but isn’t essential. Most of us are juggling a job, often a family and not many spare hours, so one plan that treats the gym and the roads as a single budget of time makes more sense than two plans fighting over the same week. It’s also a good fit if you’re coming back after a break, or you’re over 40 and want to hold on to muscle while you train.

It’s the wrong fit if your main goal is explosive power, such as jumping or sprinting, because that’s the one area where the research shows a dip. A coach who specialises in power will serve you better. And if all you want is a PDF and a start date, hybrid coaching with regular check-ins is more than you need.

What to Look for in a Hybrid Coach

Anyone can call themselves a hybrid coach, so check a few things before you pay.

• Accreditation. Ask what they’re accredited by, then check it. CIMSPA is the UK professional body for the sector, and you can verify my CIMSPA credential on its site.
• Endurance experience. Find out whether they’ve done endurance events themselves. Someone who has been through the long days and the bad patches will plan differently from someone who has only read about them.
• A plan that gets adjusted. A static PDF is a plan, not coaching, so ask how often you’ll speak and what happens when a week goes wrong.
• Fuelling. Strength and endurance together is a lot of training to feed, so ask whether nutrition guidance is part of the deal.
• Honesty about trade-offs. Doing both means neither gets maxed out. A coach who says so has probably thought it through. One who promises a PB and a bigger squat by spring probably hasn’t.

Where to Start

If you’re curious, the easiest first step is to book a conversation. It takes about 45 minutes, in person or online, and you can ask me anything about how I work.

From there, Monthly Coaching is the online plan with a weekly check-in, 12-Week Race Prep is for when you have a date in the diary, and 1-2-1 sessions in Macclesfield are for anyone who’d rather train face to face.
