ZABIDI Ghazali berjaya menjuarai lari 100 m dengan mencatat masa 10.58 saat & dinobatkan raja pecut SUKMA yang baru. Acara ini telah menjadikan emas yang ke 36 seterusnya mengukuh kedudukan Terengganu dari pungutan pingat Emas. Semangat Ne'lang berjaya mengangkat Zabidi sebagai pelari terpantas di Malaysia SUKMA KE 12 - Zabidi Ghazali dan Zabidi Ahmad, menjadi senjata utama Terengganu untuk merampas gelaran Raja Pecut Sukma di hadapan penyokong sendiri pada temasya edisi XII ini. Kedua-duanya, mungkin hanya berbeza umur dan keadaan fizikal, tetapi masing-masing mempunyai tekad yang sama iaitu pingat emas dalam acara riben biru olahraga - 100 meter.Bagi Zabidi Ghazali, 21, sememangnya gelaran pecut menjadi idaman apa lagi selepas hanya berjaya menduduki tangga ketiga di Kedah dua tahun lalu, serta mahu mengikut jejak jaguh pecut paling ternama pernah dilahirkan Terengganu, Nazmizan Mohammad. Bagi Zabidi Ahmad pula, dia mengakui peluangnya dalam 100m mungkin tipis tetapi mahu bertindak sebagai 'pengacau' bagi memberi peluang kepada rakannya memenangi acara itu. "Memang sukar bagi saya kerana ada tiga atau empat pelari lebih pantas daripada saya," katanya, yang berusia 19 tahun. Apapun, kedua-dua pelari itu pastinya tidak mahu membiarkan gelaran Raja Pecut menjadi milik orang lain dan mungkin sudah tiba masanya dua Zabidi ini mengembalikan semula mahkota itu kepada Terengganu, yang kali terakhir dimenangi Nazmizan pada 2002 di Sabah.
