Half Marathon 2mr

Feeling anxious.. I think i'm way underprepared.. and it would be overtly ambitious to aim to clock between 1:40-1:50... how about not dying for a start? maybe that'd be a good starting thought.. nevertheless.. hopefully the caffiene will bring me into overdrive 2mr... the most painful is the first 5km.. after that, the blank out phase occurs and adrenaline kicks in.. well.. hope it'll be a good run..
