I rode 3 days straight from Tuesday to Thursday in the midday heat over at Griffith Park. In fact the park was practically empty which despite the heat, actually made the riding more enjoyable. I just toned down my effort to conserve energy. Only problem is keeping my water bottles cool enough. Within the hour, they go from cold to hot water!
For Friday I actually opted to go to the gym and do some strength training. Sometimes if I ride too much, I can feel myself become physically smaller with my weight shifting anywhere between 3-7 lbs. Since I'm not a pro, I definitely want to keep a good balance between cardio endurance and muscle strength. It's definitely a balancing act because doing too much of one thing (cycling or strength training) affects the performance of the other. Though I feel doing both with proper rest periods, definitely helps make me stronger overall.
