Trail running shoes are highly recommended for Spartan races. Spartan courses usually include mud, wet grass, loose dirt, hills, and uneven terrain. Road shoes can become slippery and unstable in these conditions.
Look for trail shoes with:
Good grip and aggressive tread
Drainage (so water does not stay trapped in the shoe)
Secure fit so your foot does not slide on descents
You do not need the most expensive trail shoe. Comfort and traction matter more than brand or price.
Most beginners do not need gloves. Bare hands often give better grip on wet obstacles like ropes, rigs, and monkey bars.
Gloves can help if:
You are very prone to blisters
It is very cold
You are doing longer distances with lots of carries
If you choose gloves, use thin, grippy ones, not bulky gym gloves.
Wear clothing that:
Dries quickly
Does not hold water
Does not chafe
Good beginner setup:
Technical shirt or tri top
Compression shorts or technical run shorts
Trail shoes
Tall socks (optional but helpful for rope climbs and mud protection)
Avoid cotton. Cotton becomes heavy, cold, and uncomfortable when wet.
