Which of the following is NOT an item to account for in race running events?

In race running events, several essential items are accounted for to ensure smooth operation and participant satisfaction. Race bibs are crucial for identifying participants, while start guns are necessary for officially starting the race. Awards and medals serve to recognize and celebrate the achievements of the participants, motivating them to perform their best.

Although refreshments are important for the overall experience and can play a role in post-race recovery, they are not typically a formal necessity for the race itself in terms of event management. The core logistical items primarily focus on the race's execution, timing, and recognition of participants, which are why refreshments can be considered the least essential item from the given list.
