Given the way the race has cut up, those on the hunt for Clarence House Chase betting tips are likely to be looking at alternative ways to bet on a race in which Altior is 1/8 favourite.

At Thursday’s declaration stage Un De Sceaux, hitherto the most credible challenger to Nicky Henderson’s favourite, was scratched from the race, leaving just two challengers in the Grade 1 contest, 6/1 shot Fox Norton and 14/1 outsider Diego Du Charmil.

The pair trailed home 19 lengths and 13 lengths behind Henderson’s superstar in their last meetings with him respectively, suggesting this Ascot clash isn’t going to be much of a contest.

Bettors looking for an angle to place a wager on the race might be tempted to look into a margin of victory odds, but with Altior having won by distances as diverse as 19 lengths and three-and-a-quarter lengths inside his last three races, there’s at least one more temping bet around.

Clarence House Betting tips: Altior 6/5 to break Big Buck’s jumps-race-winning-streak record

Should Henderson’s three-time Cheltenham Festival winner score at Ascot it would be his 17th successive victory over obstacles, leaving him just one short of the current all-time mark held by Paul Nicholls’ staying hurdles machine Big Buck’s.

Already 1/2 favourite in the ante-post betting in what’s likely to be his next race, the Queen Mother Champion Chase, tying the record looks like only slightly less of a formality.

If Altior’s season follows the same path as in the past two years that would mean he could break the record in Sandown’s Celebration Chase and the William Hill traders have priced him up at 6/5 to remain unbeaten over hurdles and fences for 19 races or more.

Could Altior not only break, but decimate Big Buck’s mark?

Big Buck’s was only nine, the same age as Altior, when recording the last of his victories, after which a serious injury blunted his brilliance, but Henderson’s chaser has far fewer miles on the clock, hinting that he could go on scoring for some time yet.

A 13-run stint in France and an abortive chase career contributed to Nicholls’ hurdler having contested 20 races before finding his metier and beginning his winning streak.

By contrast, Altior raced only three times before beginning his streak over obstacles. With this in mind, the 20/1 about him extending his winning sequence to 23 races doesn’t seem so fanciful.
