What Makes BRITAX Marathon Different?

An Easy-to-Adjust Design That Grows with Your Baby

The Britax Marathon car seat  boasts an easy-to-manage design and enhanced features that can be safely used in cars with or without the LATCH (Lower Anchors and Tethers for Children) system. For one, it provides built-in lock-off clips that keep the seat tightly in place when using only traditional seatbelts at installation. Secondly, a simple handle pull allows the car seat base to be reclined when rear-facing, and soft padding and a stain resistant, removable and washable cover keep things cozy and stress-free.

In addition, the five-point harness system is made with strong polyester webbing, has tangle free straps, and fits snugly over your baby’s shoulders, collarbone and hips to provide a secure fit. There are also four adjustable height positions so the seat can truly grow with your baby. Finally, the one-hand recline adjustment allows for proper positioning, which helps ensure your child’s safety.

HUGS for Optimum Safety and Support

When it comes to safety, the Britax Marathon car seat truly delivers. First, the patented floating HUGS (Harness Ultra Guard) system exceeds U.S. safety standards by reducing forward head movement as it gently cushions the neck and chest with soft padding–a feature that’s particularly important both in the case of an accident and during nap time. In addition, this system better distributes the webbing loads, reducing head movement and minimizing harness irritation on baby’s neck in case of an impact. HUGS also reduces the chance of improperly positioning the chest clip.

Versa-Tether for Additional Security

Britax Marathon also offers Britax’s patented Versa-Tether, an anchor aid that provides additional security in the forward facing position for children weighing more than 50 pounds. The Versa-Tether fastens the top of the car seat to factory installed automobile anchor points, minimizing the possibility of a head injury in the event of impact. This system also allows for rear-facing tethering to help keep the seat consistently stable.

Weighing 16.5 lbs, and measuring 19.5 x 27.5 x 25.5 inches (WxHxD), the Marathon is also Federal Motor Vehicle Safety Standard (FMVSS) 213 compliant, meaning it adheres to a strict set of quality control and safety standards, and is approved for airline travel. The Marathon comes with a 1-year limited warranty.

Most Helpful FAVOURABLE Review

Don’t get me wrong….I would own nothing other than Britax seats at this point. We have 4 children and we’ve tried various models. We’ve donated the others to Goodwill. We currently own 5 Britax car seats for 4 children. We have 2 Regents, 1 Parkway(used as a spare), 1 Marathon, and 1 Roundabout. I feel as though I’m a walking advertisement for Britax and we’ve been accused of being uptight about car seats.

As far as I’m concerned, there are three main features that we look for in a car seat:

1. Does it fit securely in the vehicle?

Forward facing, this seat is awesome. We don’t have the latch system in our van, so we never had the opportunity to use the latch belts although I’m sure they work fine. We use the shoulder belt and we’ve never seen any other seat get as secure as our seat. When we try to move the seat side to side, the van moves instead. The beauty of the system is that after you’ve tightened the lap part of the belt down as far as you can, you then slide the shoulder part of the belt into a slot that latches down on the side of the seat. Once you’ve done this, the belt doesn’t develop any slack. Then for good measure, you attach the tether to the underside of the rear of the seat (or a tether hook in some cars). This seat doesn’t move after that.

Rear facing, the seat could be improved. This is why the seat doesn’t get 5 stars from me. The side lock down mechanism is tightened more by the thickness of the belt. Unfortunately, it can pop open without much pressure. (As a side note, the lockdown on the side of our older Roundabout works great. It is a different design. I’m not sure if Britax thought they were improving and have changed the design or if they have a different lockdown on this seat.) The annoying thing about this is that you have to continuously check to see if it has released.

2. Condition of the straps is important. I haven’t seen one manufacturer compare to the quality of the straps. The shoulder straps are thick and wide. They don’t fold up on themselves or get tangled. They are also wide across your child’s shoulders.

3. Child’s comfort. The side guards around the head are great for when they are getting tired and the safety foam is the same as you would find in bike helmets.

Overall, the seat is great. If I could have given it 4.5 stars, I would have. The rear facing problem was minor to us because we could use our Roundabout rear facing, but for someone who needs to use it rear facing for a while, it might be more of a problem. I’m hoping Britax improves that one thing, but overall, this seat is highly recommended by me.

Most Helpful CRITICAL review

This is a good car seat, with some observations.

Older children may not fit into the Marathon, as the base is too tall and they’re likely to outgrow it in height way before they reach the 65 lb weight limit. In contrast, the Roundabout has a lower weight limit (to 40 lbs) and may be a better choice if you’re transitioning from an infant seat.

The Marathon seat is shallow and the crotch strap is too short, especially for toddler boys. The Marathon measures 6 inches from the back of the seat to the base of the strap. The Roundabout is deeper, 7 inches from seat back to the base of the strap, which is perplexing. Why would Britax make the larger seat shallower, if it has to fit both infants and older children?

Second, the quick release of the Marathon is so easy to use (gently lift the metal part under the front flap) even a toddler can do it- if they fiddle with it they can loosen the harness while strapped in! Teaching the child the meaning of “no” and placing safety pins on the flap are possible solutions but not what one would expect on an expensive car seat.
It helps to tuck the excess straps between the BRitax and the car’s seat.

Please note that some models of the Marathon have a flap with velcro that’s easy to lift. The Marathon Greystone sold by Target has a slightly different flap (the metal clasp is still underneath but hidden by a flap that’s sewn on the sides – not velcroed like the picture). This looks like an improvement, as most Marathon models have the velcro version. I don’t know if the amazon model has this new flap.

The Roundabout has a different harness release system (button) and you need to press hard to release it which makes it more child proof.

Lastly, the Marathon and the Roundabout are handwash & drip dry only according to the owner’s manual and care instructions attached to the seat.

It’s a good seat for young toddlers, not so much for older ones, especially boys.
