My main betting will remain focused on the smaller stuff, but on here let's have an old fashioned play at the big races. I'm not going to bother with staking or measuring or reviewing. This is for fun and glory.
The Welsh Grand National
This seems like the sort of day where there could be no finishers. Expect to see about three horses walk through the fourth last and swim from there. So I'd guess it would make sense to keep the two previous winners on side, especially given their trainers, 10/1ish seems fair.
That said, younger horses tend to win this and the one I keep looking at is Red Devil Lads, who I saw gallop relentlessly through the mud at Ffos Las one day last year. Rebecca Curtis looks to have her horses in better shape than they were and 16/1 each way first 5 is the main bet.
That done, you then notice Sean Bowen is riding her other runner, who either wins or pulls up, so I guess we'd best save on him, and do the exacta. Then of course you also have to save on the Harry Cobden mount, even being topweight, because that's what needs to be done in all big handicaps until the end of the season.
Then, if you want an interest through the day, Richard Johnson doubles at Kempton should do the trick.
