Organisers of the Hastings Half Marathon are due to decide whether the race will go ahead after police destroyed chemicals which were discovered nearby.
A 28-year-old man was arrested after explosive chemicals, which police said posed “a threat to life”, were found at a property on the A259 Marina in St Leonards on Thursday.
Sussex Police confirmed on Saturday they had carried out a “controlled burn” on the chemicals.
The force had also discovered about 500 additional cannisters containing chemicals that are “not considered to be explosive”.
The popular Hastings running event, which had more than 3,000 runners taking part last year, was due to take place on Sunday and a final decision will be made on Saturday afternoon.
Organisers of the half marathon said they “do not want to cancel the race until the last possible moment”, adding that the situation remained “fluid”.
A spokesperson for the event said: “Your safety, along with that of our supporters and volunteers, is our top priority.
“In agreement with the authorities, we are continuing with the course setup while we assess the situation further.”

A Sussex Police spokesperson said: “Searches are continuing this morning for any other hazardous materials in the house, to ensure the house is clear of explosive material and the area is safe.”
Authorities have added there is “no indication the 28-year-old man arrested intended to cause harm either to himself of anybody else”.
They said he has been detained under the Mental Health Act while inquiries continue.
