Tumbl events

Swim better,
together.

We're building a swim community where getting better happens together.

Why we do this

Getting better shouldn't mean going it alone.

I love swimming, but it can be a solitary sport. You put in the lengths on your own, and it's hard to know if you're actually improving.

I started Tumbl to get people better feedback. These events are the other half of that: a chance to swim with other people, pick up real things to work on, and meet others who love it too.

Good coaching, good company, and you leave swimming a little better than you arrived.

The first one

A morning in the pool at Oasis.

For our launch, we teamed up with Hard and Smart Coaching for a coached freestyle session at Oasis pool in Covent Garden. Twelve swimmers, two coaches, video of everyone's stroke, and coffees with the group to finish.

Oasis Sports Centre · 31 May 2026

“It was amazing to come away from a session with clear things to work on. The coaching was brilliant: very clear instructions, and I loved that they targeted different parts of the catch and pull. I really, really loved speaking to people who also love swimming. It feels like a really nice community could be built through sessions like today. Reflecting on this morning I was like, wow, that was a ‘cup filling’ kind of interaction.”

How it ran

What the morning looked like.

90 minutes of coaching

Freestyle technique with Charlotte and Greg. Small groups by pace, focused drills, eyes on every stroke.

Video of every stroke

We filmed everyone in the water, so each swimmer left with footage on their phone to upload to Tumbl.

Coffees after

We headed to a nearby cafe with the group to chat swimming. The bit everyone said they loved most.

Run in collaboration with Hard and Smart Coaching. Charlotte coaches with Tumbl; Greg Divall is a triathlon coach and two-time GB Age Group world silver medallist.

What swimmers said

More from the morning.

“Fantastic coaching. Love the expertise and the good mood Charlotte brings.”

Swimmer · May 2026

“As a coach it was great to see other coaches doing something they're clearly passionate about. Well planned, well delivered, with just enough to take home without feeling overloaded.”

Visiting coach · May 2026

“Really good vibes from everyone.”
