What is the best daily trainer for marathon training?

If you’re training for a marathon, one of the most common questions we hear at Sportlink in Norwich is:

“What is the best daily trainer for marathon training?”

The honest answer?

There isn’t one single “best” shoe.

But there is a best type of shoe - and the right fit for you.

We spoke to Sportlink store manager and experienced marathon runner Mark Thorpe to break it down.

What should a daily trainer for marathon training do?

A daily trainer for marathon training should:

• Provide high levels of cushioning
• Protect your legs over long mileage
• Fit properly (especially in length and width)
• Offer stability when fatigue sets in
• Help you recover faster between runs

As Mark explains:

“There is no one-size-fits-all. It all depends on what actually feels right on your foot.”

Marathon training isn’t just about race day - it’s about logging consistent miles week after week.

Your daily trainer is the shoe you’ll spend the most time in.

Why fit matters more in marathon training

Marathon training changes your feet.

Over long distances, your feet can expand by up to 5%.

That means the shoe that feels “fine” over 5K may feel cramped at 18 miles.

Mark advises:

“You want roughly a thumb’s width from the front of the shoe. If you don’t, you’ll probably end up losing some toenails.”

Key fit guidelines for marathon daily trainers:

• A thumb’s width in front of your toes
• Not too snug in the forefoot
• Secure in the heel
• Room for foot expansion
  

This is especially important for runners building towards 3+ hour marathons.

What type of shoe is best for easy marathon training runs?

For most marathon training miles, you want what we call a daily cruiser.

These are:

• Cushioned
• Comfortable
• Stable
• Designed for high mileage

Examples include models like:

• Brooks Glycerin / Glycerin Max
• ASICS Gel-Nimbus
• New Balance 1080 or More v6
• HOKA Bondi

All major brands now offer this category.

These shoes:

• Absorb impact
• Protect tired legs
• Make back-to-back runs more manageable

Should you use a super trainer for marathon training?

In recent years, a new category has emerged: super trainers.

These use advanced supercritical foams (similar to carbon-plated race shoes) but without being full race-day models.

Mark explains:

“Super trainers don’t beat your legs up so much. They help reduce fatigue and allow you to recover a little bit faster.”

They are ideal if:

• You want something lighter than a traditional daily trainer
• You’re running under 3:45 and want versatility
• You may even prefer to race in it rather than carbon

All major brands now produce a super trainer option.

These shoes balance:

• Cushioning
• Responsiveness
• Reduced fatigue

What about stability for slower marathon runners?

Stability becomes more important the longer you’re on your feet.

As fatigue sets in, your form naturally changes.

Mark recommends:

“Look for something with a nice wide platform. A little bit of stability most definitely helps over something you’re rocking about on late in your runs.”

A wider base:

• Improves balance
• Reduces wobble
• Supports tired legs
• Helps maintain form in later miles

This is particularly helpful for runners at a more “sedate pace” or targeting 4+ hours.

So… what is the best daily trainer for marathon training?

The best daily trainer for marathon training is:

• Cushioned
• Stable
• Properly fitted
• Suitable for your pace
• Comfortable over long mileage

There is no universal winner.

There is only the right shoe for your foot.

Why try your marathon trainers in-store?

• Assess your gait
• Check sizing properly
• Allow treadmill testing
