The 40 horses competing in the Grand National

1, Hedgehunter, R Walsh, 20-1 - Fifth consecutive appearance for the 2005 winner, also second carrying 11st12lb in 2006. Only ninth last year but seems in better form this time and Ruby Walsh stays loyal to him. Photograph: Tom Jenkins/Guardian

2, Hi Cloy, T Doyle, 66-1 - Won the Melling Chase at this meeting two years ago, but yet to tackle the Grand National fences. Possible stamina limitations, as his best form has been shown over 2m4f. Photograph: Tom Jenkins/Guardian

3, Knowhere, J Tizzard, 50-1 - Sent off at 100-1 in last year's race and was already in trouble when unseating his rider at the eighth fence, the Canal Turn. Stable jockey Paddy Brennan prefers Fundamentalist. Photograph: Julian Herbert/Getty

4, Mr Pointment, S Thomas, 18-1 - One-time ante-post favourite following his length victory from Bewleys Berry in Becher Chase over the National fences in November, but broke a blood vessel next time out against Cloudy Lane. Photograph: Julian Herbert/Getty

5, Turko, R Johnson, 25-1 - Good form in Grade One races at Leopardstown and Cheltenham, but does not look an out-and-out stayer and the National is not a race for six-year-olds: the last to win way back in 1915. Photograph: Julian Herbert/Getty

6, Madison De Berlais, T Scudamore, 66-1 - One of several seven-year-olds in the race, and another age group with a moderate Grand National record - Bogskar, in 1940, was the most recent winner of that age. First run over the Aintree fences. Photograph: Julian Herbert/Getty

7, Simon, D Elsworth, 12-1 - Disputing second and going well when he fell six fences from home last year. Not so well handicapped this time, but has been in good form this season without managing to win. Photograph: John Walton/PA

9, Iron Man, C Williams, 100-1 - Useful chaser on his day, but has been well below form in recent outings and has failed to get round in two attempts over the National fences. Looks one to leave alone. Photograph: Graham Lee/Getty

10, Fundamentalist, PJ Brennan, 66-1 - Trainer has a good Grand National record, but this gelding does not jump well enough to suggest he can maintain it. Stamina limitations, too, for one more effective at shorter trips. Photograph: Julian Herbert/Getty

11, Butler's Cabin (right), AP McCoy, 16-1 - Yet to shine in three outings this season, but step up in trip will suit last season's Irish Grand National winner. That has been a good Aintree guide of late, and Tony McCoy is back on board. Photograph: Andrew Redington/Getty

12, Slim Pickings (right), BJ Geraghty, 10-1 - Close third last year and preparation has been geared towards Aintree again, mixing hurdling with chasing in favoured manner of Irish trainers. Good run over inadequate distance latest start. Photograph: Julian Herbert/Getty

13, Chelsea Harbour, DN Russell, 14-1 - Stamina not an issue, as he showed when winning the 3m4f Grand National Trial at Punchestown by seven lengths. But his best form is on soft/heavy ground and he could be outpaced today. Photograph: Martin Lynch /Freelance

14, Vodka Bleu, P Maloney, 40-1 - Improved performer since equipped with blinkers this season, but three miles may be as far as he wants to go. Well beaten over the National fences in last year's Topham Chase. Photograph: Julian Herbert/Getty

15, L'Ami (right), MA Fitzgerald, 33-1 - Ran well when third behind An Accordion at Cheltenham, but has been discarded by Tony McCoy after last year's race, when he ran out of stamina and finished a well-beaten 10th. Photograph: Tom Shaw/Getty

16, Snowy Morning, DJ Casey, 20-1 - One of the best handicapped runners, but jumping problems have surfaced and he could find the National too arduous at this stage. Passed over by Ruby Walsh in favour of Hedgehunter. Photograph: Martin Lynch /Freelance

17, Bewleys Berry, D O'Regan, 14-1 - Bold jumper of the National obstacles, and looked unlucky to come down at Becher's second time round last year when in front and going strongly. This has been his target ever since. Photograph: John Walton/PA

18, Contraband, K Mercer, 500-1 - Former top novice chaser, won Arkle Trophy, but at his best over two miles and sad to see him trying the toughest test for a chaser now that his best years are behind him. Photograph: Tony Marshall/PA

19, McKelvey, TJ O'Brien, 20-1 - Pushed Silver Birch all the way to the line last year, but finished lame and it remains to be seen how much ability he retains following two well-beaten runs over hurdles in March. Photograph: John Giles/PA

20, Joaaci, JW Farrelly, 66-1 - Won a valuable handicap chase at Cheltenham last season off this mark, but largely disappointing since. Needs to produce a career-best performance to be in the shake-up Photograph: Tony Marshall /PA

21, Point Barrow (falling), A Dobbin, 25-1 - Former Irish Grand National winner, started 8-1 co-favourite here last year but departed at the first fence. Tends to get behind in his races and may not be right type for Aintree. Photograph: John Giles/PA

22, D'Argent, R Thornton, 25-1 - Tough stayer who has been slugging it out in marathon chases for some time, but this is his first attempt at the National fences. May be too late for him, but chances if he takes to it. Photograph: Robert Thornton/PA

23, No Full, JR Barry, 100-1 - Seven-year-old with just two wins over fences and has plenty to prove at this level. Rated doubtful runner until pleasing his trainer when second over 2m4f on latest appearance. Photograph: Tom Shaw/Getty

24, Baily Breeze, PW Flood, 66-1 - Represents the trainer who won last week's Irish Grand National with Hear The Echo, but this nine-year-old is very much an outsider after poor efforts on his last two starts. Photograph: Racingfotos.com

25, Bob Hall, N Fehily, 100-1 - Well-bred son of Sadler's Wells, but seems to have lost his way completely and one win from nine runs over fences does not look the profile of a potential National winner. Photograph: Julian Herbert/Getty

26, Cloudy Lane, JM Maguire, 5-1 - Unseated his rider in last season's Irish Grand National, but has otherwise looked an assured jumper and rates a worthy favourite after completing his hat-trick in good style at Doncaster. Photograph: John Giles/PA

27, King Johns Castle, P Carberry, 20-1 - The subject of sustained ante-post support in recent weeks, yet Tony McCoy has rejected him in favour of another JP McManus-owned runner, Butler's Cabin. Interesting contender just the same. Photograph: Dave Thompson/PA

28, Mon Mome, A Coleman, 33-1 - Lightly-raced this season and looks to be finding some form judged on his latest Cheltenham effort. Second in last season's Welsh National, so good chance he will be staying on at the finish here. Photograph: Julian Herbert/Getty

29, Cornish Sett, N Schofield, 100-1 - Looked to be going places at one stage, but just one win in the last two seasons and has been found out in stronger company since chasing home Sir Rembrandt at Cheltenham in November. Photograph: Julian Herbert/Getty

30, Naunton Brook, A Tinkler, 66-1 - Tough customer to get past when he gets his own way out in front, something highly unlikely today. Led for much of first circuit before pulling up before 23rd fence here last year. Photograph: David Davies/PA

31, Tumbling Dice, TGM Ryan, 100-1 - Without a win since December 2006 and highly unlikely to figure over a trip which is a complete unknown. Stable has far better prospects with the fancied Slim Pickings. Photograph: Tony Marshall/PA

32, Backbeat, K Renwick, 66-1 - An 11-year-old with comparatively few miles on the clock, but possibly at his best on right-hand tracks - he was a good winner at Sandown in January. Ran over hurdles last time. Photograph: Tony Marshall/PA

33, Comply or Die, TJ Murphy, 10-1 - Winner of the 4m1f Eider Chase at Newcastle, so stamina not an issue, and form claims on his second to Cloudy Lane at Haydock. Chances provided he does not get too far behind early on. Photograph: Tony Marshall/PA

34, Idle Talk, B Harding, 50-1 - Able performer, but too many "unseated rider" in his cv to inspire confidence over the National fences. Among the backmarkers when getting rid of his jockey at the 19th fence here last year. Photograph: Julian Herbert/Getty

35, Kelami, F Keniry, 40-1 - Good second behind Gungadu in the Racing Post Chase at Kempton last time, and comes into the race in better form than 12 months ago when pulled up before two out. Photograph: John Walton/PA

36, Milan Deux Mille, TJ Malone, 100-1 - Big ask for this six-year-old to get involved in the finish, but to his credit he handled the National fences well for his age last season when fifth in the Topham Chase. Photograph: Rebecca Naden/PA

37, Nadover, RM Power, 150-1 - Chance ride for Robbie Power, successful on Silver Birch last year. Getting this one round will be an achievement in itself for the Irish rider, as Nadover reserves his (meagre) best for Chepstow nowadays. Photograph: Ian Smith /PA

38, Black Apalachi, AJ McNamara, 50-1 - Has shown reasonable form in stayers' chases in Ireland without looking a National winner waiting to happen, and is on a long losing run stretching back to December 2005. Photograph: Tony Marshall/PA

39, Philson Run, D Jacob, 25-1 - Genuine stayer, but will need soft ground to slow the others up if he is to have any chance of improving on last year's fourth placing, when 15 lengths behind third-placed Slim Pickings. Photograph: Alex Livesey/Getty

40, Dun Doire, R McGrath, 25-1 - Hesitant jumps at the early fences quickly put this Irish raider out of contention last year and he was pulled up before four out. The application of blinkers will need to have a dramatic effect. Photograph: John Walton/PA

8, Ardaghey, D England, 100-1 - Late substitute with little chance of making presence felt. Has failed to complete in two of his last three starts, and was well behind Kelami and Simon at Kempton in Racing Post Chase. Photograph: Stu Forster/Getty
