I am wondering if people who participate in athletic events are so competitive that they compete to be the first to sign up! I have just heard from the Barrathon – the Isle of Barrathon Half Marathon on June 29 – where all 250 places were snapped up in just six minutes.

Katie, who looks after registrations, was stunned by the fast uptake and offers condolences to those who didn’t make the entry list. She says: “There is a waiting list, so anyone who wishes to join it can do so at. You often find that a few people withdraw their entries closer to the day for a range of reasons so it is worth a try on the waiting list.”

The waiting list can be found at SiEntries

World triathlon qualifiers

If you tried to get a place in the Olympic distance World Triathlon Championships qualifiers this year there’s a high chance you were disappointed. So far two of the three qualifiers have been announced and all places disappeared in hours.

The Chester Deva Triathlon already had 800 entries and then added another 400 places to the entry list because of demand and all these were taken up too. There are still 84 people who wish to enter and who are still waiting on an extra list.

 Southside Six run

Entries for the Southside Six – a running race through six of Glasgow’s Parks in November – also sold out in hours. Nick Vaughan, who organises the event, said he was astounded by the interest in the race after only two years inexistence.

 Kinross Cycle Sportive

And no sooner had the Kinross Sportive, in Fife, announced the opening of entries and it was sold out. The sportive takes place on April 27 and I watched Facebook messages as cycling friends suggested entering then very quickly realised that hundreds of cyclists across the UK had thought the same. Within hours the race was full. There are currently 222 on the waiting list!

Tell me about other events that have filled up in record time.
