All the info you need to know from the Betfair markets on the first day at Cheltenham...
13:30 - Supreme Novices' Hurdle
Betfair Starting Price: [42.0] (ISP 25/1)
Antepost High of Winner: [1000.0]
Notable In-Running Highs and Lows: The winner, Labaik, matched at a high of [55.0] in-running, the runner-up, Melon, traded at a low of [1.9].
Comments: Notorious slow starter Labaik, who has refused to race three times in his last six runs, swoops late to land the spoils under Jack Kennedy. Long time antepost favourite Melon hit a low of [1.9] in running after travelling smoothly for most of the way but had no answer once the winner swept by.
14:10 - Arkle Challenge Trophy
Betfair Starting Price: [1.26] (ISP 1/4 Fav)
Antepost High of Winner: [10.0]
Notable In-Running Highs and Lows: The winner, Altior, hit a high of [1.74] in-running, the late faller, Charbel, hit a low of [2.54].
Comments: Not the slickest round of jumping we've ever seen from last year's Supreme Novices' winner but he did the job nicely in the end. Front runner Charbel was in the process of running really well (hit [2.54] in running) when coming down two out.
14:50 - Ultima Handicap Chase
Winner: Un Temps Pour Tout
Betfair Starting Price: [11.6] (ISP 9/1)
Antepost High of Winner: [24.0]
Notable In-Running Highs and Lows: The winner, Un Temps Pour Tout, was never matched higher than [21.0] before or during the run, the runner-up, Singlefarmpayment, hit a low of [1.36] and the third, Noble Endeavor hit a low of [2.2].
Comments: It's back to back wins in the Ultima for the well backed Un Temps Pour Tout who found plenty for pressure to win under Tom Scudamore. Strong-travelling favourite Singlefarmpayment hit a low of [1.36] in running and the well fancied Noble Endeavor hit [2.2].
15:30 - Champion Hurdle
Winner: Buveur D'Air
Betfair Starting Price: 6.35 (ISP 5/1)
Antepost High of Winner: [240.0]
Notable In-Running Highs and Lows: Petit Mouchoir touched [3.05] (BSP [8.0])
Comments: Buveur D'Air was always travelling well under Noel Fehily and was a ready winner. Petit Mouchoir jumped well from the front (hit 3.05 in running) but was no match for an easy winner. Strong favourite Yanworth didn't jump fluently and never had the pace to challenge. My Tent Or Yours has now been placed in three Champion Hurdles (place BSP 4.41).
16:10 - Mares' Hurdle
Winner: Apple's Jade
Betfair Starting Price: 4.52 (ISP 7/2)
Antepost High of Winner: [15.0]
Notable In-Running Highs and Lows: The winner, Apple's Jade, hit a high of [80.0] in-running, the placed horses, Vroum Vroum Mag and Limini, were matched at lows of [1.53] and [1.55] respectively.
Comments: The market principals came to the fore turning for home and the gutsy Apple's Jade fought off all challengers to win. The well fancied Willie Mullins pair Vroum Vroum Mag (1.53 in running) and Limini (1.55 in running) filled the places.
16:50 - National Hunt Novices' Chase
Winner: Tiger Roll
Betfair Starting Price: 27.3 (ISP 16/1)
Antepost High of Winner: [48.0]
Notable In-Running Highs and Lows: The winner, Tiger Roll, hit a high of [34.0] in-running, Edwulf, pulled-up in the closing stages, traded at a low of [1.52].
Comments: Tiger Roll, winner of the 2014 Triumph Hurdle at the Festival, tanked through the race under Lisa O'Neill and was an impressive winner. Edwulf (1.52 in running) and What A Moment ([8.0] in running - BSP of [230.0]) crept into contention and looked like playing a hand but the winner was too strong. The winner completed a magnificent treble on the day for Betfair Ambassador Gordon Elliott.
17:30 - Novices' Handicap Chase
Winner: Tully East
Betfair Starting Price: 9.32 (ISP 8/1)
Antepost High of Winner: [32.0]
Notable In-Running Highs and Lows: The winner, Tully East, hit a high of [21.0], of the placed horses Powersbomb was matched the lowest in-running at [2.2].
Comments: Tully East, fourth in the Martin Pipe last year, stalked the pace and won really well. Powersbomb (2.2 in running), Two Taffs (3.5 in running) and Gold Present (3.1 in running) went well but were no match for the winner.
