4 running and triathlon events in Jefferson Township, New Jersey

After a full course assessment yesterday, we’ve made the difficult but responsible decision to postpone the Mahlon 5 & 10 Miler.

Dan, an experienced and very tall trail runner, completed the course in 2.5 hours, which is well outside typical conditions. After conferring with Morris County Parks, we agree that postponement is the safest option for our runners, volunteers, and staff.

Your Options

Participants may choose one of the following:

1️⃣ Defer to the new date: March 21

2️⃣ Run Virtual and receive your swag by mail

3️⃣ Transfer your registration to another Live Run Give event

(Excludes the triathlon and partner races)

We appreciate your understanding as we prioritize safety and trail preservation. Mahlon will be waiting for us with better footing and maybe a surprise mud bath.
