A marathon block is months of early alarms, long Sundays and sessions you'd rather skip. The RunnerVits Marathon Box takes the guesswork out of what you take alongside it.

Whether it's your first marathon or you're chasing a PB, it's the full system in one place. Whatever your pace. Whatever your distance.

The Marathon Box: 30-Day Marathon Supplement System

Everything a marathon runner needs, in one box, every month. Built around the full training block (the early alarms, the midweek sessions, the Sunday long run), The Marathon Box brings together Morning Runner Essentials, Pre-Race Performance, Runner Joint Support and Sleep & Recovery, with a 30-day supply of each. Vitamins C, D3 and B12 support your immune system and help reduce tiredness and fatigue through big mileage weeks.

Pre-Race Performance is there for the sessions and race days that count. Made in the UK, Cologne List® tested and backed by science, it’s designed for runners who commit to the whole block, not just race day, and want to reach the start line feeling ready. Buy it once, or subscribe and save so next month’s box arrives before you run out.

faq

Who is the Parkrun Bundle designed for?

The Parkrun Bundle is designed for regular parkrunners who want to feel better, run faster, and stay consistent week after week. Whether you’re chasing a new 5k PB or simply want to enjoy parkrun without niggles, this bundle supports daily health, joint resilience, and pre-run performance.

How should I take the supplements on a parkrun day?

Take Morning Runner Essentials daily with breakfast. On parkrun mornings, take Pre-Race Performance around 30–45 minutes before your run. Joint Support can be taken daily later in the day with food to support joint health and recovery.

Can I take all three supplements on the same day?

Yes. The bundle is designed to work together safely and effectively. Each product targets a different need — daily nutrition, pre-run performance, and joint support — making it ideal for regular park runners.

How long before I’ll notice results?

The Pre-Race Performance capsules work acutely and can be felt on your first run. The benefits of Morning Runner Essentials and Joint Support build over time — we recommend consistent use for 4–6 weeks for best results.

Is this bundle suitable for vegans or vegetarians?

The Runner Essentials and Recovery & Sleep capsules are suitable for vegetarians. The Pre-Run formula is also vegetarian-friendly. However, the Joint Support is not suitable for vegetarians or vegans.
