The first team squad were put through their paces in the first training session in Ireland on Monday.
The Peterborough United squad were put through their paces in a tough training session on Monday afternoon in Ireland.
After an injury prevention session with physiotherapist Chris Burton, the players then moved over to the grass facilities at Malahide Football Club where they completed a technical session under the watchful gaze of manager Darren Ferguson, assistant manager Kevin Russell and coach Gary Breen.
All 28 first team players who are on tour completed the session before returning to the team hotel for dinner.
Midfielder Danny Swanson, who spoke to PUTV following training, said: 'It was a hard session, but that is what pre-season is all about. There is a lot of running involved and then you go into the technical sessions where it is all about keeping the ball so it is tough.
'We have a game on Tuesday so I am sure the lads will get 45 minutes under their belts and that will be good. It is good to get away with the lads and put the work in,' Swanson said.
The Posh under 18s trained on Monday evening with Academy manager Dave Robertson and under 18s manager Gavin Strachan taking the session.
