Josh Bradley, Ross Allen, Baz Collier and Greg Bradley have been training hard for months by hitting the gym and taking their first sprinting steps at local park runs. But why?
The team have already done amazingly and so far they've raised £760 for people living with HIV.
We caught up with Lisa Bradley, a director at Gap Solutions, to ask her how the team was getting on.
'We're supporting the Sussex Beacon at the Brighton Half Marathon on Sunday because they're a fantastic local charity that is in need of support. Being local it's an added bonus and inspiration!
We're excited for the Brighton Half Marathon and it's already created a great atmosphere at work! It's had a positive lifestyle influence on us - all of our families are looking forward to seeing our hard work pay off and have the chance to show their support.
We took on all sorts of training sessions together. We;d train at home, circuit training, short street runs and Parkruns. Two of the team had never run in public before yet they have thrown themselves into training. They've had such a positive reaction from taking part in a Parkrun. It has given them a great confidence boost.
Hopefully we can raise some money and inspire each other to make healthier choices. Some of the team are not your typical participant and they've inspired others. We're all super proud. Just by taking part it has given us all a positive focus for the start of the year as a business!'
We can't wait to see the team absolutely smash their target for fundraising! We're sure they'll surpass their expectations for their own running time at this year's Brighton Half Marathon corporate relay!
