Coaching a track team, organizing a field day, or just want some batons for relay race practice? This set is perfect. You get two relay batons and a whistle. The batons are made from lightweight but strong aluminum alloy. They're about 29cm long (11.4 inches), with an outer diameter of 3.8cm (1.5 inches). The surface is anodized and colored, so it's corrosion-resistant, won't fade, and feels smooth for a good grip. They're hollow, which is standard. The blank surface also means you can write on them with a marker or even engrave them for team names if you want. The included whistle is great for the coach to signal starts, stops, or during practice. Remember, in a standard 4x100m or 4x400m relay, each of the four runners carries the baton for one leg and hands it off within a zone. Dropping it or passing outside the zone can mean disqualification, so practice is key! These are good quality for school teams, clubs, or community sports events. A simple, essential piece of track and field equipment.
