50-1 Ultragold gives Tizzard stunning 4,334-1 treble
Harry Cobden makes his Grand National debut on Saturday but the teenager already knows where the winning post is after triumphing on his first attempt over the National fences.
The 18-year-old leads the conditional standings after a season that has been so successful he can no longer claim.
His Randox Health Topham Chase ride Ultragold had shown little since winning a 2m chase at Newbury in November, finished ninth at 100-1 in the Grand Annual at Cheltenham and he was among the 50-1 outsiders this time.
Yet to Cobden he wasn't a no-hoper and after getting Ultragold to the front at the turn into the straight the pair held off Katnap on the run-in to win by a length and seal a 4,334-1 Aintree treble for trainer Colin Tizzard.
Cobden, who rides Just A Par in the National, said: "I was looking forward to this all this week and I actually fancied the horse. Even though he was a 50-1 shot I thought he had a little squeak.
"He'd won a chase over three miles. He'd run very well last time and the handicapper had dropped him a couple of pounds.
"I had a lovely run down the inside most of the way. He jumped like a buck, was very clever and was a dream horse to ride around there. The fences ride better than they look."
Cobden, attached to the stable of champion trainer Paul Nicholls, has a lot of history with Tizzard, who he used to hunt with.
"I think I started hunting with Colin when I was seven or eight," he said. "We've known each other for quite a long time and it's great to have winners for him."
Following victories for Pingshou and Fox Norton that announced a return to form for the Tizzard team, which endured a blank Cheltenham Festival, Ultragold was a more unlikely success for a syndicate that includes Native River owners Garth and Ann Broom and Terry Warner of Rooster Booster fame.
Tizzard said: "He cost a pound or two and wasn't what we thought we were buying, which was a three-mile-two horse, but he has won a lovely race today."
He added: "Harry hunted alongside me as a little boy for a long time and I was just thinking three out, just sit still, but I didn't have to say it because he did it. He has got a brain on him and I bet he enjoyed this. His mum and dad will have as well."
Daryl Jacob was stood down after a fall from Ballykan and will have to pass the doctor to ride on Saturday. So too will Liam Treadwell, who took a heavy fall from Bright New Dawn.
After emerging from the medical room Treadwell said: "I'm a bit tender but will be fine for the National."
