In reply to Kelloggs77:
I don't know how the route looks like in winter, if similar to summer - it's well trodden and relatively safe*
There are obvious things to keep in mind:
- get up in the first lift, give yourself some time to let some guided groups first but then try to follow them closely
- watch out in the descent - people sometimes don't descend the zigzags, but run directly down to the plateau - when solo, however tempting, I'd stick to the zigzags in descent
- although it seems a bit of a joke for such short route, check the weather. In fog or dense clouds, the Breithorn is really dangerous as you can wander off the path on the plateau towards the cracks and completely loose orientation. Also, as the peak is such small effort, at least with good weather you can enjoy the views which are superb!
Have fun

* - as in Alps, there's never perfectly safe route, even less when going solo. So, I wouldn't expect anyone giving a yes/no answer - and I am a bit surprised people doing so lightly - the question is always a balance between danger and safety
