Running Road intervals 29:57 6.76 km (4:26 / km) +1m 4:26 / km
ahr:156 max:178 shoes: NB M890 Blue
First interval session in a while.
Warm up - 2km.
20x 30secs on 10 secs off.
Warm down, slowly back to the flat.
The intervals were a little harder than I had expected, I didn't check the session on my watch properly. Thought it would be 30 seconds rest, not 10.
