Tennis anyone

...I had a big training ride planned for today after work...2 hours of over/under intervals...(under and over my lactate threshold based on my heartrate)...But, my daughter wanted me to play tennis with her up at the High School...how could I resist...Instead hit the trainer around 9pm and got my work out in. Did 3x12 @155/164 alternating ever 3/2 minutes...after a 30 minute warm up.
