I am doing a complete icf walkout basement (not stick framing the walkout part).  The frost coverage here is 4ft, so at the walkout part the wal is going to be 13 or 14ft depending on wether I go 4ft or 5ft on the frost wall.  problem is I only have 10ft braces and want to do this all i one pour, remote area don't want to pay for pumps etc twice.  I am confident in my block  so my issue is how to do the bracing.  I was thinking running 2x6 0r 8 horizontally at 3 or 4 ft high with vertical 2x4s every 4 ft from the footings up to the 2x6.  Then attche my braces at the top of the 2x6 as I normally would on the footings.  Any sugestions?

thanks for the suggestions I have double strongbacked the tall walls and am happy with the results.  my next problem is that I have used all my braces up and on a large portion of the wall I have 10 foot braces with 12 ft walls ( owner decided to change grade levels after starting).  I dont want to remove the braces I have already installed so what can I do to make up the 2 feet so that I can straighten the top and keep it secure.  My idea is to use 2x4 and extend it to the top of the wall from the braces and tie into the ladder.
