legs feel like lead - lungs full of "tar" - 30r20 70% HRR

Must be a race coming up - legs felt useless this morning - which I wouldn't mind if I trained hard yesterday but all I did was a bit of house cleaning! Haven't trained since Friday - combine that with lungs coughing up crap and its a pretty miserable affair this training malarkey. Still completed the piece so that's good :o)
