    Make your time in the vertical world easier and safer.

    The dual-pattern sheath on the Sterling Marathon Pro 10.1mm Rope makes the line's center point stick out like a sore thumb and saves you tons of time on climbs and descents. Quick identification of the center point ensures both ends are equal when you're making the fifth rappel in a row, and lets you know if you have enough rope to lower your partner off the 15-bolt sport route he just sent. You'll love the easy rope management provided by the dual-pattern the next time you're re-stacking line at a hanging belay. The Sterling Marathon Pro is also extremely easy to clip thanks to its 10.1mm diameter, and its light weight of 63g/m won't weight down your pack when you head out on another alpine approach.

    My first rope. Still going strong

    • Familiarity: I've put it through the wringer

    Got this as my first rope years ago. This is a great workhorse rope. I used it a bunch for TRing and working sport routes. The sheath doesn't even show that much wear compared to my other ropes. It still feeds through Grigri2 ok and doesn't get coily either. Sterling makes a great product.

    Great Rope So Far!

    • Familiarity: I've used it several times

    I've been able to take the rope outside to the local crag as well as climb on it in the gym a few times and it has felt great. I haven't taken a fall on it yet, but it has been easy to work with and I like the color on it. It is a little difficult to tell that it is a bi-pattern as the two patterns are a little too similar in my opinion so I would recommend using a rope marker to mark the center. Give me a call if you have any questions or would like to see how the rope is wearing after more use. I'll post an update once I know more. I should not I bought the 70M bi-pattern version.

    Great Rope So Far!

    Great rope, poor color choice on my part

    • Familiarity: I've used it several times

    So I bought the 60M digital cammo color because it was on sale. Big mistake. I now see why it is on sale. It's supposedly bi-color but it's not in any way discernible especially when stressed or on the wall. Go with orange or Blue, or even better is the Sterling 9.8mm rope. Visuals aside, Sterling makes an amazing rope you can depend on.

    I'd trust this rope with my life...

    • Familiarity: I've used it once or twice and have initial impressions

    Strong, relatively light weight and reliable. I'm highly satisfied with this purchase. I haven't had the chance to use it as much as I would like, but one notable feature that I enjoy is the ability to distinguish the midpoint of the rope based on the slight pattern change.

    Great rope.

    • Familiarity: I've used it several times

    This is the third rope I've owned. It has been great so far! I've packed it with me on some rough approaches and it didn't feel super heavy which was nice. I got the 70m which has been great for longer routes. The only thing I don't like is that the pattern change in the middle is not noticeable. Inside it was somewhat noticeable but outside, in the sunlight, it is impossible to find the center based on the pattern change. But performance wise, this has been a great rope.

    So far so good

    • Familiarity: I've used it once or twice and have initial impressions

    I haven't used it outside yet, but so far it seems great. I like this brand of ropes and I loved the color and was in the market for a 70m rope. This fit the bill and as a clean rope seems great. I'm confident it will hold up great when I start putting it to the test!

    Best rope I've bought, yet!

      This is a fantastic rope. Very supple for a 10.1mm and very light per meter.
      Weave transition leaves no doubt about the center point and the sheath is thick and durable.

      Not sure what magic allows for such nice feel in a cord this durable, but I’m not complaining.

      Also, shipping was shockingly fast.
      Well done!

      Awesome Rope, worth the price

      • Familiarity: I've put it through the wringer

      These ropes are super soft to the hands, super durable, strong, and the bicolors on these are the best!! Really impressed with the quality of these ropes.


        Not having to guess where the middle of the rope is awesome! Purchased for ice climbing in Ouray. Can confidently say the rope doesn't get fat when wet and dries quickly especially after the ends of the rope went for an unexpected swim in the Uncompahgre river. At 10.1 the rope feeds surprisingly well through most belay devices.

        Great rope... just check the length

          When I first opened the bag and flaked the rope I noticed the center mark/pattern switch was off. I thought it was maybe a meter off but to my surprise, after measuring four times, my 70m rope is actually over 75m with the extra all on one side. I am certainly not complaining about the extra length, it's definitely going to be handy when it needs to be cut. I just hope their isn't someone out there 5m off or short.

          Otherwise, I've only used it twice but so far I'm very happy.

          always tied up, never let me down

          • Familiarity: I've put it through the wringer

          My Marathon Pro rope has been great for years of outdoor lead climbing. It's lighter than any other 10.1mm rope and is as supple as any 9.8mm. The 9.8 Sterling Velocity is only lighter by 1g per meter, and the extra durability from the 10.1 is totally worth it.

          Get the dry coated sheath for that extra longevity since the Marathon Pro 10.1 doesn't get fat, AND it can take tons of heinous falls with a lighter impact force and great catch. My favorite rope! Can't go wrong with Sterling Marathon Pro 10.1!

          always tied up, never let me down

          Outstanding rope

            This was my first rope and I couldn't be happier with it. Despite being 10.1mm, it is very supple and works well with a gri gri II. It's perfect for sport, trad and top roping. You won't regret the investment!

            Great Rope

            Sterling has made an outstanding rope here! We have it in the dry 70m and work it everyday! tough, light, great colors for easy mid point detection. andd a great sleeping pad if need be.

            Great Rope

            Solid Rope.

            • Familiarity: I've put it through the wringer

            I purchased the 70M Green variant of this earlier in the year. Absolutely love this rope. It's a favorite among my climbing partners...but that might be more a case of them not wanting wear on their ropes. Mooches.


            I love the fact that it's Bi-Patterned. It is super handy, we were in Maple and from the belay station on the route you lose sight of the climber completely. By watching the bi-pattern I was able to figure out that she had gotten slightly off route.

            My main complaint about the bi-pattern is that both sides are predominantly green. So with some wear and tear the rope turns dark and it's slightly harder to tell the difference. Not a major problem, but if the sides were drastically different colors, that'd make it easier.


            The 70M rope has been so much better and more handy than any of the 60M's. 70M all the way.


            It's a 10.1 dia, can't go wrong there. It's thick enough that it'll take a good amount of abuse, but thin enough that it's not a pain. This rope didn't swell at all with use. A bunch of friends have mentioned their ropes swelling a tad, but I haven't noted anything with this one.


            So far, this has been great and incredibly durable. I've only had the rope for about 5-months but it's not showing any signs of wear.


            When I bought this, there were a few snags in the sheath and I'm curious about the durability of it. Nothing to return the rope over, but something to note.

            Great rope. Don't get Digital Camo.

              Really love this rope. The handling is great, and the durability is admirable.

              The Digital Camo coloring, however, is not great. The difference between the two patterns is pretty subtle -- thereby kind of ruining the point of the bipattern (i.e., easy to find midpoint for setting up a rappel). And the problem only gets worse after the rope gets dirty.

              We have a Sterling 9.8 bipattern where you can *feel* the midpoint very easily, but with this rope's dry treatment, the whole thing feels pretty smooth -- midpoint included.

              Anyway, overall, a fantastic rope. Just really wish we'd gotten the green bipattern.

              Couldn't be happier!

              • Familiarity: I've used it several times

              I have climbed on this rope several times now in the unpredictable Montana weather and I can say that it has stood up to the test very well. Last weekend I was climbing with a large group of friends and everyone fell in love with this rope. The rope proved to be very durable and perfect for sport climbing. I would highly recommend this rope to friend.

              Great all around rope

              • Familiarity: I've put it through the wringer

              This rope is a great! Durable, but still very pliable. Strong but still light enough to use on harder projects. I have the 70M and its great for long multis/bigwall. I'v climbed on a lot of different rope brands and sterling is by far my favorite! Worth the money.

              In the tech specs, it says: "Dry Treatment:...

              In the tech specs, it says: "Dry Treatment: [DRY] yes, [STD] no". Does this rope have a dry sheath and/or a dry core? What Sterling technology is used; DryCoat and/or DryCore?
