If I were to risk assess my Relays that are normally last Thursday evening in June at this moment in time it would be:
Hazard - COVID 19
Risk - Possibility of infection from another competitor, official, spectator or member of the public.
Risk Rating - Low
What control measures can be put in place - don't come if you are concerned about this. Anyone with any symptoms of illness advised not to attend in any capacity. No officials/marshalls over the age of 65 will be involved.
But of course I would need the Govt's general assessment done first, allowing me to make my localised one and then the participants to make their own personal assessment.
