I know he's well past his best and may not even get into the race but Bun Doran 50/1 NRNB is a little bit interesting at a big price.
Being 11 years of age he's probably not a lot to hide from the handicapper, but he's been running well enough, and is slightly better off with some and a lot better of with others at the weights that he has already run against this season, that are a fair bit shorter than him in the betting for this race.
His actual Cheltenham Festival form is OK, without quite being good enough to win a race. He was 6th of 20 in the 2017 Close Brothers Novice Chase, 2nd of 19 in the 2019 running of the Grand Annual, 3rd of 5 in the 2020 Queen Mother Champion Chase, before being disappointing last season when 13th of 19 in the Grand Annual. However, on that run last season, he was rated 150, and was in pretty poor form all season, which was unlike him.
The good thing about the poor form was it meant his rating started to drop a fair bit. He's now rated 131, 19lbs lower than when in the race last season. He was rated 160 just 2 seasons back, although that rating was probably a little bit unfair/high based on his actual form. He is due to run today, and if he wins he'll get a 5lb penalty which he would most definitely need to have any chance of getting in the race.
I'd give him an E/W shout off 136, at a big price, in a race that has thrown up the odd surprise in it's time.
I've just added him this morning @ 56.5/1 (boosted with Hills).
I've also backed him for today E/W as I think he'll be 'trying' today.
