Riverside Theatre continued Nicky Henderson’s amazing festival with a thrilling victory in the Ryanair Chase.
The 7/2 chance had to dig really deep on the run-in to deny Albertas Run a hat-trick of wins in the Grade One event, giving Henderson a sixth success of the week and jockey Barry Geraghty his fifth.
Tony McCoy asked Albertas Run to make all the running but was hassled all the way by Irish raider Rubi Light, while the eventual winner had anything but a trouble-free run in the chasing pack.
Albertas Run (10/1) still led descending the hill, where Riverside Theatre was upsides for the first time.
Rubi Light was the first to give way but Medermit (8/1) threw down the biggest challenge two out, and may even have led after the last as Albertas Run went right.
But Geraghty got a great response from his partner, conjuring one last lunge to get up close home and deny the brave 11-year-old by half-a-length, with Medermit a similar distance away in third.
Poquelin was withdrawn at the start having been kicked in the mouth.
