Ngotho ran on the European road running circuit in the early 1990s and had wins at the 1993 Alsterlauf Hamburg and the 1994 Kerzerslauf. After a win at the Cross Pradelle, she returned to international competition at the 1995 IAAF World Cross Country Championships and her fourth-place finish behind compatriot Sally Barsosio brought her another team gold medal. Running on the track circuit that year she set two lifetime bests: she ran 15:24.53 minutes for the 5000 metres in Hengelo and a 3000 m best of 8:50.09 minutes brought her eighth place at the 1995 IAAF Grand Prix Final in Monaco. She remained a top-ten finisher at European track meets over the next few years.
