The AJ Bell Great Manchester Run is back on Sunday, May 31, with a sold-out half-marathon, a still-open 10K and a city-centre route that organisers have been refining for the third year in a row. Great Run, the event organiser, confirmed this week that the 13.1-mile race had reached its 16,000-runner cap with five weeks still to go — the earliest a Manchester half has ever sold out — and that the 10K would now carry the event's elite-field designation, with the half-marathon framed as the mass-participation showcase.
The split is a deliberate strategic call. By moving the elite money into the 10K, Great Run can attract a sharper, more televised field on a course that finishes on Deansgate, while letting the half-marathon focus on charity entries, club runners and the city's lively pacing-group programme. Both races begin and end in central Manchester. The half-marathon route now passes both the Etihad Stadium and Old Trafford in a single loop, a piece of choreography that organisers have been quietly proud of since first dropping it into the course rotation in 2024.
The 10K's elite line-up has not been formally announced, but Great Run has confirmed that the field will include British marathon team representatives coming off London. Mahamed Mahamed, who set the British men's marathon record at London earlier this month, has indicated through his agent that Manchester is on his "active list" for May, alongside several of the British women whose marathon programmes have just closed. Last year's 10K winners Phil Sesemann and Calli Hauger-Thackery have also entered. The TV broadcast on the BBC, which now covers both races back-to-back, has been extended by 30 minutes to accommodate a longer post-race interview window.
For ordinary runners, Manchester remains the easiest UK city-centre half-marathon to spectate, and the event's now-21 entertainment zones have become a quietly defining feature of the day. The 24 zones planned for the half-marathon route this year include the Beswick brass band stand, the now-traditional Salford samba block and the Old Trafford choir. The 10K route, with 21 zones squeezed into a shorter loop, is becoming the more intense of the two for atmosphere, and several charity partners have flagged that they are deliberately allocating more cheer-zone resources to the 10K to compensate for the half being closed to new entries.
Manchester's jump in demand mirrors a wider UK pattern. The London Marathon set a Guinness World Record of 59,830 finishers earlier this month, the Brighton and Manchester half-marathons are both selling out earlier than ever, and parkrun has logged a fifth consecutive year of growth at its UK events. Great Run executives have publicly framed the May 31 sell-out as a leading indicator that the post-pandemic UK running boom is still very much intact — and that, with the half full a month early, demand for autumn entries is likely to test the limits of the country's road-event infrastructure all over again.
