Towcestrians are up to second in South West One East after winning their third game in a row, 24-10 away at previously second-placed Swindon.
Both teams took a while to settle in the blustery conditions, but it was Swindon who made the breakthrough when Adam Westall notched a penalty.
Tows replied immediately, however, as the backs swiftly spread the ball to Matt Yuill, who scored the first try of the match, before Harry Hopewell went through a gap in the Swindon defence for a second as the home team found themselves under intense pressure.
Tows were now in their prime and scored a third try before half time through captain Sam Sturley, giving the visitors a 19-3 half time lead.
Despite now facing the wind, Tows went over again as Sturley scored his second and the visitors saw out victory, albeit after a consolation try from Hayden Ambler. Tows travel to Witney this weekend.
Elsewhere, Tows IIs lost to Bugbrooke and the Colts were beaten by Olney, but the IIIs won 38-13 over Old Laurentions.
