We have protocol in place that works like this:
One entry point for all trainers
Wash or hand sanitise at track provided washing station BEFORE unloading horses
Use your prearranged X ties - a gap of 5 metres between different trainers
Fill in their own notebook with who is on site, what time you arrived - this is our contact tracing requirement - no unlicensed staff on site
Hose bay use - hand sanitiser to be used before touching hose bay taps or hose - provided at the hose bay
Fill in notebook as you leave
hand sanitise before loading horses to leave
easy really but we are a small track who have all worked together to get back on track.
