Went to the crunch today.
On the journey I listened to Herve x Kissy Sell Out Mash Up Mix but on Crunch FM channels there was also Jaguar Skills  (free downloads) and Electro Swing that I can recommend.
I got drenched in sodium, chlorides, ammonia, bit of glucose and some H2O
It took 42 minutes to get to the crunch. I didn't like the journey but I'd actually like to go again.

My directions to the crunch
Straight on a Tabata after the junction for Warm Up
8x 20sec - 100% effort, each effort followed by 10sec recovery
Go easy through the town of Zone 2 for about 5 minutes
Now do go to long interval lane and follow directions as below
2 min - at threshold
1 min - easy
90 sec - hard
1 min - easy
1 min - flat out
1 min - easy
30 sec - flat out
1 min - easy
1 min - flat out
1 min - easy
90 sec - hard
1 min - easy
1 min - flat out
Go easy through the town of Zone 2 for about 5 minutes
Turn left and do another tabata and really make it count
Have a 5 minute picnic
Repeat the long interval lane combo (as above) and nearly immediately after getting to the end of the lane, you'll arrive at the CRUNCH

The crunch looks different to everyone. This is what is looked like to an outsider putting their head around the door of my garage.
