However, a young Gloucester side, who featured two 16 year olds in Tyler Jerrum and Ollie Thorley, fought back well after the break scoring 12 points against Leicester's 17.
Junior Academy Manager Simon Lane accepted that his side had been second best on the day, but that they had improved massively even during the course of the game.
"It was a great opportunity for the boys to play at Welford Road, the biggest occasion of their rugby lives for some of them.
"We were taken a bit by storm in the first half. Credit to the Tigers, they're the most organised outfit we've come up against, and their group have been together for several years now.
"We made four errors in the first half and they scored from every one. The second half was a different story though.
"We came into our own and started playing our game. We established good field position from good kicks from Reece Boughton and Tiff Eden, the forwards really stepped it up and the second half actually finished 17-12.
"It was a big learning curve against a well established side who have provided several players for Leicester's A League side this season. But we kept going and scored tries from Lewis Ludlow and Jonny Hill.
"What's important now is how we respond to this. We've got Newcastle at home at Hartpury on Saturday (kick off 2pm). They've beaten Worcester, they're a good side and will pose a real challenge, but we'll be looking to bounce back."
