Upper Heritage - Anaerobic Intervals

The plan was for six two minute anaerobic intervals at about 440 watts....

Could only manage three and blew up half way up the fourth....

Definitely this is my weakest area.. Go forever (comparatively speaking.. 10-15 minutes anyway) at 350 watts... Get over 400 and at two minutes I'm done for...

Finished with an eight minute threshold interval, about 320 watts. Even that was hard after the others... :-(
