Sonic Dash - the free-to-download iPhone and iPad app - is speeding through its first global challenge over the coming weeks. It's a challenge so epic that Sega has teamed up with Pocket-lint to give away an equally epic prize to one lucky reader: a 16GB Apple iPad.

The first ever global challenge in Sonic Dash gives players the chance to take part in a co-operative, global event, with the goal to run the combined equivalent of 100 laps around the world - or a total of 2,490,100 miles for those counting. You won’t be alone, as every participant’s runs will contribute to the total distance completed and if the challenge is completed before the curtain falls on 5 August then all players will receive Shadow the Hedgehog as an additional playable character.

Run as Sonic or one of his friends across stunning 3D environments as you dash, spin and jump your way through the levels at high speeds - all those metres and miles count. Fans of our spikey blue hero will find the classic hazards, enemies and loop-the-loops familiar in this fast-paced, free-to-play infinite runner title.
