Race Marshals and the procedure when groups come together

We have a shortage of marshals for the 17th of May Race at Allscott Cricket Club. If you are coming with a Friend Parent or Partner can you ask them if they can assist, as the last thing we want to do is cancel.
Also we had 2 accidents last week, we believe this was when chasing groups came together.
Just to clarify to everyone especially riders  new to the league the policy is:
When a chasing group catches you move over to the left and let them pass. You then go to the join the back of their group. When you catch a group they will let you through to go to the front. take care “RIDE SMART”
THIS IS A STRICT PROCEDURE AIMED AT REDUCING CONFUSION AND INJURIES
Thanks
