The organisers of the Henley Half Triathlon have increased the number of places available for the 2012 edition of the race, after a huge oversubscription for the closed-course race.
There are also a limited number of relay places available after numerous requests were made for team entries.
The Henley Half uses the same course as Challenge Henley, and includes a 1.2-mile swim, 56-mile bike and 13.1-mile run through Henley-on-Thames and along the Thames footpath.
The additional places will be available from 9am on 6 January.
Entries cost £150 (affiliated, £155 unaffiliated) and £200 for Team entries.
