Isabella's father was a farmer but is now deceased. She is married to road racer David Maina.
In 2001 she joined the Kenya police force, where she benefited from team training. At the end of the summer season she came under the tutaledge of coach Billet, who saw enormous potential in results of physiological tests performed on Ochichi.
Friends of Isabella recommended her to manager Gwenael Vigot in 1997, she then entered nine small road races in France that year, of these she won eight. Her 1998 season was however interrupted by a severe bout of malaria.
Isabella went into the 2004 Olympics in good form and performed up to expectations. She took the lead in the race in an effort to burn the kick out of Ethiopia's Meseret Defar, who was sitting on her shoulder. Meserat however was too strong and sped past Ochichi around the final turn. Isabella hung on for a well earned silver medal.
