Dom’s Health Stack

What's your name and what are you known for?

I'm Dom Maskell and I was the co-founder of Runna.

What health advice would you give yourself 10 years ago?

Just sleep. I was 21 and did not get the quality of sleep I needed. Gaming, phone, emails late at night — then you wonder why you can't sleep. Having a wind-down routine and really focusing on sleep would be the main thing.

What's in your gym bag?

Running trainers, my sports tracking watch, and a Runna subscription — but that doesn't fit in the bag. Favourite shoe brand is On Running — full suite of their trainers. For race day, still the Nike Alphafly 3s.

What's your ideal morning routine?

It changes every single day. I've got two operating systems — part of me wants routine and part of me hates it. Sometimes I'll wake up super early for a run and a proper cooked breakfast. Some days it's complete chaos. But the constants are: shower, breakfast every day, and getting outside for exercise before work.

Bold health take?

Everyone should just keep it simple. There's a stat about the amount of people stressed trying to be well. I really like Bryan Johnson for this — even with 200 supplements, he says nail sleep, food, exercise, time with friends. Don't have as many supplements as me.

You're in a new city — what do you do for a workout?

Running. I use Strava's route functionality to find where all the locals run, then just go explore. Easy run, see the city, sometimes hit the trails. Lovely.

Favourite brand in health that's not Runna?

Heights. Find out about Dan Murray. They nail the keep-it-simple mindset — three supplements, take them in the morning, clear guidance. Beautiful bottles. People are busy enough. Read the instructions, follow them. Done.

Supplement you can't live without?

Heights. I take all of them — Magnesium, Vitals and Probiotic. All great. You get some good deep sleep.

What's the next big thing in health?

The personalised aspect. Personalised blood tests, personalised PT programmes, personalised running plans — looking at you as an individual, seeing how you're responding, and saying what does this person need? Not what are the 1,000 things this person could do.

Are you using AI for that?

Yeah, ChatGPT and Claude. I put in my blood tests, supplements, check for contradictions. It knows my previous results. But someone should be coming to me saying — hey Dom, tie your blood test with your WHOOP data with other people like you. That's where the future is.

Worst health advice you ever followed?

All the stuff on Instagram. Generic advice where one thing worked for someone but didn't work for me. Like heavy gym sessions at 6am — the blood drains from my brain. Half passing out, half falling asleep. Just doesn't work for me.

Where does your health money go?

Running clothes and shoes. Private blood tests every six months. WHOOP, Garmin watch. Metric-driven stuff that gives me good outcomes. I don't do crazy supplements and nootropics until they're more evidence-based.

Any rules you live by?

Eating well and eating non-processed foods. I literally lived on ready meals and Huel ready-made drinks for three years. Now I try to have whole foods — enough protein, carbs, veg. It's stuff everyone knows but somehow no one does.

Health goal this year?

Get my running back to where it was when I first started Runna. I was PBing across every distance — the most amazing feeling. Then the business got busy and running plateaued. Now I'm really excited to be PBing again following the Runna app properly.

Best place you've ever worked out?

Cape Town. The most amazing city for running — interval sessions up and down the promenade, top off, warm morning, everyone else running. Just amazing.

Who should we follow?

The only one I follow is Bryan Johnson. Very interesting guy, keeps it simple. But I try not to follow too many because you end up thinking you should do all 20 things. I prefer to focus on myself.

Health trend that's BS?

I'm not fully sure I'm qualified to speak on that. There's a lot of noise around nootropics but maybe they work, maybe they don't. I'd rather take the few things proven to work.

Dream sauna lineup?

You'd be in there for sure, Will. Bryan Johnson with his ice pack on. And Richard Branson's got to make the cut.
