2.40 Perth - Boyhood
Elder says: "The 2.40 at Perth is a handicap chase over 3m 6f and 121 yards. As ever for the Highland National, it's going to be a pretty stamina-sapping contest.
"Something - I think - will suit Boyhood, who has got a decent record on good ground - when getting genuinely good ground - he's only ran on it, actually, twice in his career.
"He's finished second on both occasions, one of them early on in his career, one of them a few years ago at Cheltenham, but he's a horse we don't see all that often.
"The Tom George yard are in good form - Ciaran Gethings rode a winner for Tom George in these colours earlier on in the week with Another Stowaway at Ludlow.
"I think Boyhood could be another one after that good third in the Tim Maloney [handicap chase] at Haydock last time around.
"Chef D'oeuvre ran ok for a little way - the winner of that race in the Scottish National just last weekend.
"I think Boyhood can go a couple better. He's not won for a while, but he is very well handicapped off a mark of 127.
"And it's just about time for Boyhood to win once again. I think there are a fair few other dangers in the race - the Ben Pauling horse - I thought - was of interest, second last time around behind Peur De Rien, that was a decent run, and Peur De Rien didn't run too badly just the other day.
"I do think though, it'll be finishing second again, as he has done the last twice, that's Big Difference in the green and red silks, but I do think Boyhood is very much the one to beat.
"As I say, stamina [is] the name of the game in the Highland National, Boyhood can come home in front."
1.40 Doncaster - Autumn Flight
Elder says: "Sprinters in action for the 1.40 over at Doncaster, five furlongs the trip, and a pretty small field - just the five of them going to post.
"I'm going to side with one of the two five-year-olds in the race, Autumn Flight, who is likely to be a fairly short price favourite, but I think he's very well handicapped.
"He's won his last two at Chelmsford, that's since joining his new yard of Robert Cowell.
"I do think that Autumn Flight is capable of a fair bit more. [He] won off a mark of 80 last time around - up to 83 this time over.
"Rhys Clutterbuck - I think he's going to be one of the leading riders in the apprentice ranks this season - takes a further five pounds off, so effectively - strictly talking on weight terms - he's two pounds lower than last time out.
"Yes, he did hang right on that occasion, that was coming off the bend. He did get pressured for the lead and things didn't exactly go right for him on that occasion.
"But I do think that was a fair run, and up three pounds, he could've been a fair bit more harsh, the handicapper, so I think Autumn Flight is still progressive. I think he'll take a fair bit of beating.
"Secretinthepark ran a decent race last time around, as did Tanasoq - they were both in good contests behind Arecibo and with Tanasoq, up at Musselburgh, but I do think Autumn Flight's got a bit more to come.
"I think he could be a handicapper worth watching for this season, so Autumn Flight in the 1.40 at Doncaster."
2.15 Doncaster - Pop Master
Elder says: "The 2.15 at Doncaster is a fascinating little contest, with - I would imagine- a fair few improvers coming out of this in the long term scheme of things, but none more so than Pop Master.
"I think he could be a pretty useful horse for the Ed Walker team this season, as he showed on his latest start at Pontefract.
"That was his first start on turf. [He's had] three starts prior to that including a couple of successes were all on the all-weather.
"But, I do think Pop Master is better than he showed last time around. Yes he finished second, [but] he did engage in a bit of a pace battle on that occasion.
"Normally at Pontefract, that's where you want to be, but Bickerstaffe came from off the pace [and] picked them up late on, and Pop Master was left back in second. He did beat the rest rather comprehensively.
"So I think Pop Master is capable of a little better.
"Keep in mind the Kevin Ryan runner, that's Seven Brothers. I think he'll go fairly close, he's still open to a fair bit more.
"And the Roger Teal runner, Whenthedealinsdone, he's only had one run on good ground so far, that was a success. He was beaten at Salisbury last time around, but [on] a much softer surface. I think Whenthedealinsdone could be the main danger to Pop Master.
"But Pop Master looks well treated to me."
