Similar to how the 100 line marathon with no hold would work, this would be a 100 line marathon with the inability to form the Gold and Silver Blocks. This would impact the time of runs significantly by making one of the most helpful parts of a normal run inaccessible. I would love to see this subcategory come to fruition on this games forum.

I think that would be an awesome challenge to add to all three of the varieties we have already!
