Climbing 101: Guide to Top Rope Solo Climbing

Top rope solo climbing (or TR solo/TR soloing) is an advanced rock climbing technique that requires a solid background in climbing and plenty of proper guidance to avoid injury. While top rope climbing, or top roping, involves the cooperation of a belayer (a person who controls a security rope that’s attached to a top rope anchor system as well as the climber) as a climber ascends, the solo version removes the participation of a belayer.

Normal top roping involves a climber ascending while secured with a tie-in knot (the climber’s connection to the rope) to one end of the rope while a belayer and a belay device manage the rope’s slack. The solo version of this sees the climber’s connection to a fixed rope moving along with the climber.

Climbers often top rope on routes where they can reach an anchor (gear secured to the rock wall) by hiking to the top of a cliff and where lead climbing—in which one climber leads and another follows—is not an option.

Becoming proficient at top rope soloing techniques requires specific training with professionals. Here are the eight steps you’ll need to familiarize yourself with to accomplish these climbs:

1. 1. Anchor the climbing rope. Your static rope should be clipped to a solid anchor (metal gear affixed to the rock) below the top of the cliff so the rope won’t rub across any edges of the cliff. You can set up a backup anchor above the cliff and then the primary anchor below the cliff’s lip. A 10 mm or thicker static rope is recommended for security and longevity. It may be helpful to pre-clip long slings (a type of versatile climbing gear) to the anchor, which you will use at the end of your climb.
2. 2. Coil excess rope. Back at the bottom of the climb, coil the extra rope, letting it hang above the ground. You may also use a water bottle or other weight at the bottom of the rope to add tension, which will help your self-belay system slide up the rope more smoothly at the beginning of the pitch, a term for the first section of a climb or big wall.
3. 3. Set up the self-belay. It’s recommended you use two different devices. While the second device is technically a backup device, the redundancy is important for safety. These two devices should be attached to your rope, per the device instructions. Make sure the cams (protection gear you can anchor in crevices) for each device are properly locked onto the rope.
4. 4. Attach the self-belay devices. Clip the self-belay devices to the rigid loop of strong, woven fabric called webbing that attaches your climbing harness’ leg loops to the waist belt (also known as the belay loop) using either oval locking carabiners (or biners) or anti-cross-loading locking carabiners. To keep the primary (top) self-belay device separate from the second device and in the best position for braking, connect it to a chest harness. You can make yourself a chest harness from either a single sling or a pair of slings, one over each shoulder, that cross in the middle. Use either webbing or an adjustable strap and the same clip-in hole as the device’s carabiner for this chest harness. This harness should not be load-bearing—it merely holds the device in position.
5. 5. Test the system. Before you begin your climb, gently bounce-test the system to make sure both devices lock properly under your weight and that the devices don’t interfere with each other.
6. 6. Climb. As you climb, you may need to push the devices along to get you started, but they should slide up the rope as you climb.
7. 7. End the climb. You should stop your climb before your self-belaying system bumps into your anchor. Once you reach your anchor, clip into the anchor using slings or personal tethers. Once you’re anchored, remove the self-belay devices from the now-unweighted rope.
8. 8. Rappel down. Attach your rappel device (a device that assists your descent by acting as a brake) to the rope and rappel to the base of the crag.

Top rope solo climbing could be advantageous for those who aren’t able to bring a partner along with them. But as an advanced technique, solo top roping is a dangerous way to climb. Without the help of a partner or rope team, you must do the proper research, training, and preparation, plus pay close attention to all backup knots and other safety checks during the activity.

Additionally, you will have to overcome the mental challenges of knowing you are climbing without the assistance and checks of others—especially in the event something goes wrong and you find yourself needing help.

Top rope solo climbing is an expert technique that can be extremely dangerous if not done with the proper guidance. Climbing and mountaineering with a rope team lend themselves to a higher degree of safety. Here are four additional tips to keep in mind when considering top rope solo climbing:

• Avoid edges. Avoid running your rope over sharp edges, which will weaken its integrity.
• Double your equipment. Using two ascender clamps or ascender devices that work differently from each other will reduce the risk of seeing both devices experience the same error, should one occur.
• Choose a straight route. Select a route that is as straight as possible to minimize the number of times the rope may chafe or get in your way when you’re climbing.
• Use a backup rope. For your safety, you may want to use more than just a single rope for safety. An auxiliary rope serving as a backup should be a dynamic rope so it can absorb the shock generated by a primary system failure.

Climbing is a high-impact activity with an elevated risk of serious injury. Practice, proper guidance, and extensive safety precautions are essential when attempting a climbing pursuit.
