I love running, some days feel hard, some days you feel great, and that’s what makes it fun. Today was a good one.

I’ve had my share of tough races over the past 12 months, so when it all comes together like this, it means a lot.

Ballarat is a great course, the half is built for fast running. Congrats to everyone who showed up today. No matter the time, getting out there is what counts.

Thank you for helping make this happen @asicsid @corosindonesia @striveindonesia taken in Ballarat, Victoria by @jackahearncoaching

Welcome to my coaching page — I’m Jack Ahearn, an Australian running coach living & training in Indonesia since 2016.

I’ve been coaching for over 5 years, helping hundreds of athletes achieve personal bests while building a genuine love for running.

I have experience working with runners of all levels — from those just starting their running journey through to semi-elite athletes.

I work with athletes from 5km through to ultra marathons. Every runner receives a highly personalised program designed to fit their lifestyle, schedule, and goals — on both road and trail.

Running is a huge part of my life, and helping you train smarter, fuel better, and reach your goals is what drives me.

Kim did us all proud with this one!

A 1 minute PB is something we’re both incredibly proud of. Kim got sick for several key weeks of an already short build, which made this prep really challenging. Once she recovered, we focused on getting in as much running as we could while limiting intensity, and on building a strong fuelling plan.

The race day plan was simple: run to effort, have fun and don’t worry about time goals. Start conservative, and if the pace feels strong, maybe a PB is possible.

That’s exactly what she did. She executed so well and got that PB!

Super proud of @hamzaredzuan for running a 6 minute PB at Melbourne yesterday!

This one has been a long time coming. His previous PB was run back in 2024, and his last marathon in 2025 ended in 3:40 and disappointment.

We’ve been working towards this for 6 months. Training in Malaysia is very challenging, but we were confident a PB was well within reach.

Great execution and a big step in the right direction. This PB was definitely earnt!!

Plenty more to come!

limindah and I have been working towards this for 6 months, and what a result!!! 🔥

We gave her a long enough build to develop her speed early in the block, before moving into a half marathon specific phase. That got her confident running fast. Never hitting race pace in Jakarta can be scary, but race day conditions are completely different, and trusting your fitness is key.

Could not be more proud. Not just sub 2, but a 1:54 and a 16 minute PB. Huge effort!

46 MINUTE PB!!!! Huge for @ikramlaliasa 🔥

A PB like this doesn’t happen overnight. At Sydney last year he ran just over 5 hours, and a lot has happened since!

We built his week around 1-2 easy runs, an interval session and a long run, with plenty of cycling around the run training. Then from 6 weeks to 2 weeks out from race day, we focused on 4 key long runs to prepare for Berlin, with much higher fuelling than in his previous races.

The result? A 46 minute PB in Berlin. Massive!

Another incredible run by @nistisaandrea at Garmin Run 2026!

In only her second half marathon, she’s taken 11 minutes off her PB in just 3 months. Even more impressive is the self-control and feel for effort it took to run a negative split, for the second race in a row.

Next up we’re spending some time training at 5K and 10K intensity before we go after a sub 2 half. Can’t wait to see what she does.

A massive congratulations to @jstmartini on running her first mountain marathon AND landing on the podium!

Hitting the podium the first time you run a distance is a huge achievement, and it comes from hard work and a real commitment to getting better.

Martini has been practising her fuelling and building time on the trails with elevation, while staying strong and mentally ready.

Even a trip and a swollen ankle mid-race couldn’t stop her from finishing and locking in an amazing result.

This is just the beginning as she builds towards BTS 70K 🏔️

Got a trail race on your list and not sure where to start? Send me a DM and let’s build your plan. taken in Lombok, Indonesia by @jackahearncoaching

Big step forward for @hambar.12 , who PB’d in the 10KM over the weekend!

He ran over 6 minutes faster and broke the 50 minute barrier, which is an important step as we work towards his half marathon in a few weeks.

Building speed and confidence over 10KM will pay off as he steps up in distance, and hopefully it sets up another PB in the half.

Chasing your own sub 50? DM me “10K” and I’ll tell you how we’d get you there. by @jackahearncoaching
