He spoke to the PA news agency upon arriving: “It feels amazing and somewhat emotional in a way.
“I think these things are always, you forget what you’re doing during it, and then you realise ‘Oh, we’ve just been doing this for the last month, and now we’re here’.
“And it’s kind of as simple as that. So it feels, overall, it just feels really, really, really good.”
Cullen, 30, said the pair have faced “horrendous wind and rain” in the past month but joked that his Birkenstocks have held up.
Along the route, which took him through areas including the Lake District, Manchester and Liverpool, he performed in quirky venues, including a sauna, and also held an intimate gig for one of his most loyal fans.
Jack added: “We went over to Liverpool, played a little gig, to one fan in particular, actually, who always comes to my shows, drives down from Liverpool to London.
“So I cycled four hours to go meet him and play him some of the new tunes face to face. So that was a really, really special one.”
While in the Lake District, he shot a music video for his new single with RCA Records, All I Need, and said he almost lost a drone and had to hike up a mountain “for a few hours” to retrieve it.
Over time, Cullen began playing his music across the UK and built a fanbase, culminating in more than 20,000 followers on TikTok.
