Olympic triathlon stars Alistair and Jonny Brownlee are both entered for the annual Daleside Auld Lang Syne Race on Penistone Hill on Monday.
Gold medallist Alistair won last year’s event near Haworth, pipping brother Jonny, who was crowned world triathlon champion in October, by 11 seconds.
Organisers are hoping they will go head to head again in the popular six-mile run, which features 900 feet of climb.
The rise to fame of the brothers attracted a larger than usual crowd last year and the race is full up once again, with more than 450 entries.
Local interest will once again centre on Keighley’s Ian Holmes – a club-mate of the Brownlees at Bingley Harriers – and his bid to claim an eighth successive veteran-40 crown.
The 12-time overall winner will have to overcome Haworth’s Andy Peace to achieve success.
Other big names in the mix include Andi Jones, Rob Hope (Pudsey & Bramley), Sam Tosh (Rossendale) and Chris Steele (Borrowdale).
Last year’s ladies winner Katie Walshaw, of Holmfirth, is again among the entries, as is Haworth GP Jo Buckley, who was runner-up in 2011.
The popular fancy dress competition will also be held.
