Climbing alone with a rope — from a fixed top rope to a self-belayed lead.
“Top solo” usually means top-rope solo. Lead solo is a different game — and clearly harder.
A rope hangs fixed from above (anchor/stance). You climb the rope — a progress-capture device locks under load.
Up top: a bomber anchor (redundancy!). Rope slack or lightly tensioned. On the harness: progress-capture plus backup. Course setup: Ropeman on one strand, a Prusik above, a rope butterfly below — Micro Traxion (with pulley) as an alternative. A neck/chest lanyard keeps the device upright. As you climb it slides up; in a fall it grabs.
Known routes, technique training, solo sessions in the gym/at the crag when a partner is missing — and you really own the setup.
Wrong anchor, device the wrong way round, no backup, rope over an edge, device jammed by body/pack, “free solo by accident” if the system doesn’t grab.
You lead as usual — clip draws — and belay yourself with a solo-belay system on the rope.
Typical: rope bag on the ground or harness, solo-belay device (GriGri-like, dedicated solo devices, or progress-capture + backup). You run the rope through the pieces; the device feeds and holds a fall. Clearly more complex than top-rope solo.
Experienced leaders who have trained solo systems — often only after plenty of top-rope solo and a clear emergency plan.
Fall factor, feed errors, device jammed/free, no backup, no help if injured. Lead solo is the hardest variant.
Two building blocks that often show up together — plus a Ropeman or Micro Traxion as the following device, always with a backup.
TAZ · Progress capture / rappelLOV3 — rappel device with progress captureCombo of rappel device and progress capture — often the core of a top-rope-solo setup. Follow the manual and compatible ropes strictly; don’t skip the backup.
Avant Climbing · Device orientationTR Solo Neck LanyardNeck lanyard for top-rope solo: keeps the solo device in place, cuts twisting and gets in the way less. Universal fit; fail-safe breakaway against strangulation.
Wild Country · Progress captureRopeman 1 — rope clampCourse setup for top-rope solo: Ropeman on one strand, a Prusik above as backup, rope butterfly below. Follow the manual and rope diameter.
Petzl · Progress capture / pulleyMicro Traxion — pulley with progress captureAlternative to the Ropeman: a following pulley plus progress capture — less friction climbing a fixed rope. Always with a backup (Prusik).Product links as examples — not a buying recommendation and no affiliate links. Always check the manual and compatible ropes.
One device is not enough. A second progress-capture, a Prusik, or the maker’s backup — and test it on the ground first.
Build it up top as if two people could fall: redundant, equalised, edge-protected. Top-rope solo lives and dies on the anchor.
Progress-capture devices lock in one direction only. Lanyard/clip so the device doesn’t flip or jam on the harness.
Before every session: a short load test just off the ground. Does it grab? Does the rope run clean? Is the backup in reach?
Where, when back, which route. Solo is not invisible — if it goes wrong, someone needs a plan B.
If the system doesn’t grab or you take it off “just for a second”, you’re free solo. Discipline: the system stays on until you’re on the ground or safe at the stance.
