The Bank of Scotland’s Great Wall of Support is back in 2017!
Using some very clever technology, your personal messages of support could be seen by runners right when they need it most, actually on the course just before the finish line straight!
Use the form below to send them a message and it could appear on the wall on the day to help motivate your friends or family members that are taking part.
You have 60 characters to make it as encouraging and funny as you can, keep it clean, and be sure to include your name and theirs, so they know it's for them!
Submit a message before 5pm on Thursday 28 September and help build a Great Wall of Support.
