+1 on this.
Also get up as early as you can. The sun rises at around 4-5 AM in the summer here and it heats up quickly. Escape that as much as you can and start your tour early. But be safe riding in the early morning on the streets and wear a reflective vest and have lights on the front and rear of your bike.
