The Flash runs fast to stop Mark Mardon, the Weather Wizard II .He runs faster and faster until he breaks the chronal barrier, travelling through time.
FUN FACT: Although this is the first time Barry travels through time in the TV show, the after effects of him tampering with the past in the future episodes are visible already.The night his mother was murdered and (possibly) the particle accelerator explosion & Barry's accident are examples of those after effects.
