Practice makes 90% accurate

I need to do some memory training. Haven't done any since the world championships, demonstrations for journalists and TV people aside, and I need to stay in shape all year if I'm going to actually win the blasted world memory championship next time round. I also need to work on memorising cards by shuffling them between my hands (like I was doing on This Morning), rather than turning them over like I normally do. I'm pretty sure I could go faster if I do it that way, but it'll take me a while to get used to it. But there's just not so much motivation to practice when there isn't a competition for so long. Anyone out there want to organise one for me?
