The annual scramble for places in the Two Castles Run will take place from midday on Tuesday (March 1).
Each year runners from across the country battle to secure one of the 4,000 entries in this ever popular race between the castles at Warwick and Kenilworth, organised by Kenilworth Rotary Club and Leamington Cycling & Athletics Club.
Places are snapped up within hours of the registration going live online, with hundreds of others joining the waiting list.
Race organiser Rotarian Philip Southwell said: “There is always a stampede for places as both the serious athletes and the not so serious recreational runners try to get their hands on an entry number. This will be our 34th year and the race has never been more popular.”
The race, on Sunday June 12, is being sponsored by Leamington solicitors Blythe Liggins for the 11th consecutive year. Joint senior partner Richard Thornton said: “It is a fantastic event and I can’t praise Kenilworth Rotary Club enough for their organisation – and for raising more than £100,000 each year for charity.
“We have been the main sponsor since 2005 and really enjoy our involvement. Most members of the firm get involved, either as runners or marshals or even manning our water station.”
Anyone wishing to register should visit www.twocastlesrun.org.uk after midday on Tuesday March 1.
