Climbing Solo Cliffs & Mountains
Mountain is hazardous.
How to Climb and Belay Alone a Multipitch Route
Rock climbing is dangerous.
Climbing alone is even more dangerous (e.g., true narrative of a solo Serious Accident in French).
I use to climb integral solo without belaying, with two gold rules : being able to climb-down every step, and no objective hazard (no stones falling, solid rock).
2008 I decided to test auto-belaying. To climb harder than 5b (my climbing-down limit). And to be able to escape from a high and long route, if my partner was wounded, and if a short section was too difficult for me to climb it alone
The method explained below is not recommended by device makers, and has no safety garanty: if you use it, it is your responsibility. According to a device manufacturer, auto-blocking funtion is made to block the second climber: rope over blocks rope under. However, when a first climber falls, the huge energy will force rope over side-by-side with rope under. The rope-to-rope friction will make rope to melt, and breal..
ONLY 2 devices, I think, are fine and safe to climb solo : Silent Partner (Wren Industries) and Soloist. But it is rather expensive ($250 ?)if you do not use it often, and too heavy (450 g) to carry it in your bag for every climb with a partner. I do not use auto-belaying frequently enough to buy it, but I think you should. You should also learn how to use them properly, and a great website is Yann Camus' BlissClimbing and his online course on rope solo climbing
Grigri is less expensive and lighter, but less safe I guess (see the Grigri solo belay: C2C 2010 in French). See also a tested system with a Grigri plus a Shunt Système Grigri + Shunt Grigri ouvert vu de près + noeud. In addition, like "my system", Grigri will not stop a climber who fall head-first (upside-down). A good evidence is shown on a Youtube video by Yann Test Of Lead Climbing Solo Devices (Part 1) (third one from page top, in English)
Well, after this necessary preliminary,let's explain: To belay I use ATC-guide or Reverso (used as the auto-blocking X, click climber on the left). They are very similar, but for solo belaying, ACT is better. "My" method, explained below, comes from Epicurie, forum C2C 2004 (in French).
1- Clip small loop of ATC or Reverso to the harness with a carabiner
2- Clip a second carabiner to a neck collar (it's better to make an-8 harness on shoulders, carabiner hanging on the sternum. Leave 3-4 fingers space between carabiners).
3- Clip the second carabiner to the rope loop (out of ACT/Reverso) and the ACT black wire or the large Reverso loop
ACT-solo system (see Reverso system down)
- One rope end is free (the "hand" side on Réverso or ACT). It will flew while you climb (secure the end with a knot)
- The other rope end (the "climber" side on Réverso or ACT) is attached to an anchor at the belay down. If the first steps from the belay are hard, insert a shock absorber or add some rope length for elasticity (tree, anchor below first peg...). Check the autoblocking properties by clipping your rope in a first anchor over your head: when you sit down, rope blocks you.
Reverso system (ACT-guide above)
- When arriving to a new anchor during the climb, pull several times on the rope attached to the belay down there, to free enough length to clip the anchor above. It's tedious, and much easier to clip the point when you are above it.
- If you fall head up, it blocks nicely the rope (see pictures above). I did not test it with great falls already.
If you fall upside-down, with head first, "my system" does not block the rope (French story of an accident on C2C website).
To block a head-first fall, it is mandatory to make a knot (or several knots) on the main rope below the ACT-guide, and shift it when possible
- This system can use a single large rope, or two thin ropes (more dynamic, but heavier).

Other Autobelaying Solo Systems
- The ONLY device I think is correct and safe is the Silent Parner, Wren Industries. But it is expensive ($250) and heavy (450g).
