When I saw that Liz gave me 296 watt intervals this week instead of the 255watts.
When I had her move my long workouts to Thursdays and Fridays.
When I hit my run paces.
When I wave at another runner, but they ignore me.
When I'm so hungry but too tired to eat.
How my flip turns feel
What they really look like
How running off the bike feels
Most importantly, how I feel when I see a step back week on my training plan.
