The best marathon deals we found this Prime Day in October

Saucony No-Show Cushioned Invisible Liner Socks for Women

4.5 star average rating from 26,686 reviews on Amazon

Stay comfortable while running with socks that stay in place as you rack up the miles. These feature padding, a smooth toe seam and air mesh ventilation – not to mention arch support for a body-hugging fit, according to the brand. According to Saucony, their silicone grip on the heel ensures they don't slip while jogging.

Shokz OpenRun Open-Ear Bluetooth Bone Conduction Sports Headphones

4.6 star average rating from 29,686 reviews on Amazon

Our top pick for the best open-back (meaning they sit around your ears rather than in them) earbuds for athletes. They're sweat-resistant and have a sleek, secure design. “They lasted the entire length of the race and I had no issues with connectivity,” says Lauren Swanson, editorial director of NBC Select, who wore them during the New York City Marathon.

Garmin Forerunner 255 Smartwatch

4.6 star average rating from 954 reviews on Amazon

Lowest price ever

What sets the Garmin Forerunner apart from other smartwatches is its long battery life; NBC Select contributor Harry Rabinowitz wore his device for an entire week without needing to charge it. It features workout tracking, stores music and can be connected to Bluetooth headphones. It also features multi-band GPS, meaning it can communicate with multiple GPS satellites simultaneously for more accurate mapping, according to Garmin.

Danish Endurance long distance running socks

4.5 star average rating from 20,761 reviews on Amazon

Lowest price ever

These quarter-length socks feature padding around the ball of the foot to minimize friction and prevent blisters, while additional compression around the arch provides additional support, according to the brand. According to Danish Endurance, they're made from a Prolene blend (Prolene is a lightweight fabric that doesn't absorb moisture) that wicks away moisture and gives a breathable feel.

Ocoopa rechargeable hand warmer

4.5 star average rating from 31,704 reviews on Amazon

Make cold early morning workouts a little more comfortable with these electric hand warmers, which feature three temperature settings and a rechargeable battery. They are about the size of a computer mouse and should fit in most gloves and bags. (Only one hand warmer is included, so double up if you want a pair.)

How I found the best running gear deals on Prime Day in October

All of my recommendations above are based on NBC Select's previous reporting and coverage. I've also included products tested by the NBC Select staff. I ran every listing through price trackers like CamelCamelCamel to ensure the products were at the lowest price in at least three months. All of the products I recommend are highly rated with an average rating of at least 4.0 stars from hundreds of reviews.

Why trust NBC Select?

I'm a New York-based freelance writer and editor who focuses on beauty, health, and gaming for NBC Select and has covered Amazon Prime Day, Black Friday, and Cyber ​​Monday for years. I'm also a casual runner, logging about 10 to 15 miles weekly. To round up the best Prime Day sales in October, I found discounted products at either their lowest price ever or their lowest price in three months.
