The Tel Aviv Municipality announced Tuesday that the city’s annual marathon would be postponed by a week, because of unseasonably high temperatures expected on Friday.

Other races, including the half marathon, are still scheduled for Friday.

According to meteorology reports, temperatures in Tel Aviv on Friday are expected to rise up to a sweltering 32 degrees Celsius (90 fahrenheit), with 35% humidity.

The city said it contemplated postponing the entire event, but asserted that such a move would not be possible because of US President Barack Obama’s visit to Israel next week.

Some 35,000 runners are expected to take part in the marathon.

The municipality said runners who were registered for the marathon but do not wish to compete next week will be compensated.

In 2011, a 42 year old runner died after suffering from a heat stroke during the 42 kilometer run. Fifteen more runners were hospitalized with heat stroke and an additional 50 were treated for dehydration.
