The main racing this week comes from just down the road at Doncaster with the St Leger meeting.

At the time of writing, the ground is soft at Donnie, and with more rain due, the going looks likely to be fairly testing all week – usually a good sign for those of you buying (betting higher) winning distances with Sporting Index.

Friday brings the third day of the St Leger festival and the highlight races are the Flying Childers Stakes and the Doncaster Cup.

The Group 2 Flying Childers is a five furlong race for two year olds and a field of twelve runners have been declared.

The 3/1 favourite is Senor Mirasol from the Kevin Ryan stable. With a Listed race win in soft ground at Tipperary last time out, this is a worthy favourite.

For those punters looking for more value, or perhaps an each way bet, Mythical Border is interesting, having had one win from her sole outing, in a class five all-weather maiden at Lingfield.

This is a big ask for this Johannesburg filly on the back of a 128-day break, but trained by Jeremy Noseda and ridden by Frankie Dettori she cannot be dismissed.

Another runner which I am sure will attract plenty of interest on course is the appropriately named Doncaster Rover.

Stewart Barr's colt ran a good race when winning a class two at Chester and assuming he handles the ground would be a good each way punt at 11/1 with Boylesports.

The Group 2 Doncaster Cup is a two mile two furlong staying contest and with the all-conquering Aidan O'Brien saddling the favourite, Honolulu, it is hard to look past the Irish raider.

A horse I do like in this race is Sagara from the Godolphin stable at around 7/1. He has won on soft ground in France and was staying on when third to Yeats at Goodwood in July.

The extra two furlongs will suit him down to the ground and the stable seems to have hit a better run of form over the last few weeks having had a quiet start to the season.

A very interesting runner is Dolly Penrose, the only three year old in the field and carrying only seven stone twelve pounds.

I think with testing conditions this will be too much of an ask for her to win, although she may run into a place at 100/1, but she is obviously held in high regard by her successful trainer and is one to watch for the future.

The St Leger, the final flat racing classic of the season, is run at Doncaster on Saturday. Aidan O'Brien has won just about every Group 1 run in Europe so far this season and his Frozen Fire is the 9/4 favourite with Boylesports for the race.

However, the Irish Derby winner doesn't look to be the most straightforward of characters and if he drops down below 2/1 on the day, I'd be happy to 'lay' him on Betdaq (becoming the bookmaker and betting that he won't win).

The value each-way bet in the race looks like Andrew Balding's Top Lock. He's been knocking on the door all season and looks sure to stay the trip and handle what could be testing ground.

He showed at Goodwood last time that he's in good heart when a creditable second to Centennial in the re-scheduled Great Voltigeur.

There is a danger that he probably lacks the necessary class to win, but at 16/1, he only needs to make the frame to give us a decent return.
