About OMM

OMM is a two-day orienteering event staged each year in the United Kingdom, organised by Original Mountain Marathon and first held in 1968. For many years it ran as the Karrimor International Mountain Marathon before taking the OMM name. Teams cover a mountain course across the two days, picking their own routes and carrying their own kit, so self-sufficiency and sound decisions in rough weather matter as much as fitness. The same name sits behind the clothing and equipment line that grew around the event: lightweight technical clothing, footwear, rucksacks, accessories and sportswear for mountain runners, ultra-trail runners and other outdoor adventurers.

Kit is built to be durable and repairable rather than thrown away. Through its RE:OMM project the brand recycles, repairs and reconditions used gear, uses recycled insulation, and sends orders out in low-ink and compostable packaging. InfiniOMM is its move toward gear that can be recycled once it wears out.

Standard shipping is free on orders over £50, and anything below that amount carries a £6 charge, with most parcels going by Royal Mail 48hr Tracked. Unwanted items can be returned by post within 14 days as long as they are unused, undamaged and in their original condition and packaging, and refunds go back to the original payment method. Membership of the Oh My Rewards loyalty scheme lets shoppers collect points as they buy.

News and updates appear on Facebook, Twitter, YouTube and Instagram.

Ways to Save at OMM

What is RE:OMM?

Original Mountain Marathon runs RE:OMM, a project that recycles, repairs and reconditions gear, and it sits alongside recycled insulation plus low-ink and compostable packaging. Mountain kit is built to last and can be repaired, so this page is worth checking for a current OMM offer.

Does OMM have a teacher discount?

Yes. OMM runs a teacher discount program, and certified instructors receive exclusive codes, typically 10% off, that they can pass on to students. Instructors have to sign up or get certified to access these benefits and starter kits.

Does OMM have a birthday discount?

Yes. Birthday perks come through OMM's Oh My Rewards loyalty program, where members earn bonus points that can be redeemed for discounts such as $10, $15 or $20 off purchases.

Does OMM have a first responder discount?

Yes. OMM gives a first responder discount to police, fire and EMT workers, and verification through ID.me is required.

Do new customers get a discount at OMM?

Yes. Eligible new customers who spend over $40 get 20% off their first order at OMM.

Does OMM have a student discount?

OMM's Official School Ambassador program offers reduced membership rates, which works as a student perk rather than a standard discount code. StudentOMT members also get 15% off a dedicated OMM question bank.

Does OMM offer free shipping?

Yes. OMM ships standard delivery free on orders over £50, while orders under that amount carry a £6 charge, and most items go out via Royal Mail 48hr Tracked.
