When out cycling finding your rhythm will help you to maintain a good steady pace and speed, and part of finding your rhythm is controlling your breathing, if your breathing is all over the place you won't be able to hold a steady pace for any great amount of time.
Also working to your power meter and cadence is another part in maintaining a good rhythm while on a bike ride, and combine all of these factors and you will start to see an improvement in your times when out on the bike.
Practice makes perfect so when your next out on a ride practice your breathing and finding your rhythm.
You should consult your Doctor before doing any strenuous exercise or workout, if you have any dizziness or pain you should stop immediately, you do this workout at your own risk. Please be reminded i am not a personal trainer this is just my workout routine you should consult a personal trainer to obtain a proper workout for what you want to achieve.
