125 miles overnight, unsupported, on a fixed-gear bike with one small bag. Time to pack some toys. Here's what I plan to take for the Dun Run 2005: Two spare inner tubes Lumicycle Li-ion/5w/12w halogen front lamps CatEye TLD600 rear lamp + 2xAAA spares Photonz 2x rear, 1x front Flagpole & "Dunwich or Bust!" flag Watch with 45-min "snack now" beeper Puncture kit Flick pliers with knife blade (cheap petrol-station Leatherman clone - expendable and useful) Cool tool (the best multi-tool in the world, ever) Spoke key Mini pump Train tickets Plenty of cash Plastic First-aid kit (optimise for blisters, hayfever, tendon inflammation, chafing, road rash, NSAIDs) Vaseline (a small vanity tin is ideal) Strapping (on long runs my ankles get ouchy: this is a me-specific) Phone (with compass and torch built in, gods I love the Nokia 5140) Snaplight Map & case House keys Power bars x4 Bonk gel Strawberry bootlaces, jelly babies or similar (sugar is good in the last hour or two) Water bottle (refill from filling stations and halfway) Loo roll in a baggie (the halfway rest stop has been known to run out) Best shorts Socks Shortsleeve jersey Lifa longsleeve base layer (when it gets colder midnight-5am, this layered with the jersey works nicely) Bandanna (warm head, minimal pack) Swimmies & pack towel (we're going to the seaside!) Contacts lenses and case Sunnies with day and night lenses Specs in case of dry eyes
