What is the best Leki trekking pole for trail running on South Downs?

The South Downs Way stretches over 100 miles (160 km) of rolling chalk hills, steep ascents, and fast descents. For trail running on this iconic route, you need poles that are ultralight, quick to deploy, easy to stash, and comfortable to carry for hours. After testing Leki’s lineup, the best pole for the South Downs is the Leki Micro Vario Carbon. Its combination of low weight, folding design, and quick‑release Trigger Shark strap makes it ideal for the undulating, mixed terrain of the South Downs. This article explains why.

Why the South Downs demands a specific pole

The South Downs are not the jagged peaks of Snowdonia or the boggy moors of the Pennine Way. Instead, you face:

• Short, steep climbs (e.g., the Devil’s Dyke, Ditchling Beacon) where you need poles for propulsion, then want to stash them quickly on the flat.
• Long, rolling ridges where poles are only needed intermittently – you need to collapse and deploy them rapidly.
• Chalky, slippery paths that require secure grip without excessive weight.
• Fast running – every gram matters, and poles must not bounce or interfere with your stride.

Leki Micro Vario Carbon – the perfect fit

1. Ultralight carbon shaft

At 190g per pole, the Micro Vario Carbon is light enough to forget when stowed, yet stiff enough to provide reliable support on climbs. The carbon fibre shaft reduces arm fatigue over long miles – crucial when you are running 20‑30 km on the South Downs.

2. Folding (Z‑pole) design

The poles fold into three sections, collapsing to 40 cm. This allows you to:

• Tuck them into a running vest (e.g., Salomon ADV Skin 12, UltrAspire) or attach them to a waist belt.
• Deploy them in seconds: a single pull locks the sections with an audible click.

On the South Downs, where you may use poles for a steep climb then run a flat ridge, this speed is invaluable.

3. Trigger Shark quick‑release strap

The Trigger Shark system is a game‑changer for runners. A small magnet or clip attaches to your glove (or a simple loop on your hand). To release the pole, you squeeze the grip – the pole detaches instantly, leaving the strap on your hand. You can then stow the pole without fumbling with a traditional wrist strap. When you need the pole again, you click it back in. This is perfect for the South Downs’ constant transitions between climbing and running.

4. Comfortable Aergon Air foam grip

The foam grip is warm, non‑slip even when wet, and ergonomically shaped. It reduces hand fatigue and provides a secure hold during fast descents.

5. Carbide tip with optional rubber covers

The standard carbide tip bites into chalk and grassy slopes. For road sections (the South Downs Way includes some tarmac), slip on the included rubber “paws” to save the tip and improve traction.

How to choose the correct fixed length

The Micro Vario Carbon is fixed length – you cannot adjust it on the trail. On the South Downs, which has moderate gradients, a fixed length works well if you choose correctly. Use the formula:

Your height (cm) × 0.68 = pole length in cm.

Example:

• 165 cm → 112 cm → choose 110 cm or 115 cm (size down for running)
• 175 cm → 119 cm → choose 115 cm or 120 cm
• 185 cm → 126 cm → choose 125 cm

If between sizes, many runners prefer a slightly shorter pole for faster arm swing.

Why not the Leki Micro Vario Alu or other models?

• Micro Vario Alu (aluminium, 230g) is heavier and will cause more arm fatigue on long runs. The carbon version is worth the premium.
• Leki Ultratrail FX.One (even lighter, 160g) lacks the Trigger Shark strap and is more fragile. The Micro Vario Carbon is a better balance for the South Downs’ mixed terrain.
• Leki Makalu Lite (telescoping, 240g) is too heavy and bulky for running.

Practical tips for using the Micro Vario Carbon on the South Downs

• Stow poles in a running vest – Many vests have dedicated pole attachment points. Practice deploying and stowing before your run.
• Use the Trigger Shark glove or loop – Leki sells compatible gloves, or you can sew a small loop onto your favourite gloves.
• Adjust length slightly by hand position – On steep climbs, choke down on the grip (hold lower) to effectively shorten the pole. On descents, hold the grip higher.
• Wash after chalky runs – South Downs chalk dust can get into the folding joints. Rinse with fresh water and dry.

Alternatives for different budgets

• Budget: Decathlon Forclaz MT500 (aluminium, flick‑lock) – heavier and no Trigger Shark, but cheap (£35).
• Ultralight alternative: Black Diamond Distance Carbon Z – similar weight (165g) but uses a standard strap, not quick‑release. Still excellent.

Final verdict

For trail running on the South Downs, the Leki Micro Vario Carbon is the best Leki pole. Its ultralight carbon shaft, folding design, and Trigger Shark quick‑release strap are perfectly suited to the rolling, variable terrain. You can deploy them for steep climbs, stash them for fast flats, and rely on the secure grip for chalky descents. While the price is high (£150‑180), the combination of weight, packability, and convenience is unmatched. If you run the South Downs Way regularly, consider this an investment in speed and comfort.
