Can't walk properly, never mind run :(

TT this morning, wasn't so good. Didnt get even close to my previous PB, the whole way I struggled; felt a bit dizzy and my leg was giving me some pain. The day didnt get any better, by lunchtime I could barely walk. By 8pm when I left work (gotta love end of financial year!) my boss has informed me he is already sick of seeing me limping around after one day and is going to make sure I go the physio tomorrow... so that told me. No intention of running tomorrow morning and probably not Thursday at this point in time either. Talk about bad timing though :(
