Ok, so the legs aren't quite ready for 60 or 90s intervals. So I'll save the planned workout for another day :)
WU: 10min easy jog
MS: 10 x(30s hard, 30s easy); + 20min race pace
CD: 5min jog
I'm having two forced days off now (my sister is getting married!), so here's hoping that come Monday, the legs will be fresh and ready for an awesome brick session!
Now, just to avoid too much champagne over the next few days..........
