Please help me with my itinerary?
The good news is that you’re in Cusco for a lot longer than most people. If you’re into hiking you can do what Eric recommended above (Rainbow Mountain) just keep in mind that is a full day experience and you should be in great shape.
Here is the itinerary I would suggest:
2 Jun / Arrive in Cusco + Free Day to explore
3 Jun / Full Day in Cusco (Plaza, Cathedral, Qorikancha, Saqsayhuaman, Tambomachay, Q’enqo, Puca’Pucara)
4 Jun / Full Day in Sacred Valley (Awanakancha, Pisac, Ollantaytambo)
5 Jun / Full Day in Sacred Valley (Chinchero, Moray, Maras)
6 Jun / Train to Aguas Calientes
7 Jun / Full Day at Machu Picchu
8 Jun / Return to Cusco + Free Day to explore
9 Jun / Visit Tipon + Andahuaylillas (or Rainbow Mountain)
10 Jun / Free Day until flight
