We modified how we were training go-outs to reflect the fact that we had a problem tacking direction, and not running straight all the way back in February. I posted a video of it here. For whatever reason we abandoned it over the summer and started again this fall.
The exercise has evolved significantly from last winter. First, we stopped using the broad jump and started using driveway markers. I have two orange ones and two yellow ones that I set up exactly the same way as the jump boards (3ft apart in a straight line). Second, we did/do have a problem with running in a straight line. We started much closer to the channels this time and have been working our way backwards at a much slower pace than we moved before. This is mostly to give Rugby the practice of running in a straight line. I think he does need to build that muscle memory to be successful. Now he is working this set up at just over 30ft away.
There was just one problem that showed itself for the first time last week. I had assumed that my yellow markers and my orange markers were equivalent. Last week, he started something new. He was running straight until he saw a yellow marker, then would change course towards it. As soon as I realized what was making him loose his straight line, a post I read over at Tip Tail popped into my head.
