Frequently Asked Questions

Is the Chiswick Half family-friendly?
It is spectator friendly, but unfortunately there are no kids races. Chiswick House is very beautiful and the race is run along the river so it's a lovely day out for the family. But, unfortunately there is only the half marathon distance, and the roads are not closed.
When will I receive my race pack for the Chiswick Half?
Race packs will need to be collected on the day from the registration tent situated between Chiswick House and the cafe.
What is the cut-off time for the Chiswick Half?
There's a cut off time for the half marathon of 3 hours (180 mins). After this, you can still run to the finish but there won't be marshalls or timing available.

    This is a beautiful course! But no course markers. It would be good to have a sign every mile as it helps with pace and motivation. Other than that we really enjoyed it!
