Brighton 10K 測試日：Alphafly、Alphafly 2、Vaporfly、Suunto Race 與 Polar Vantage V3

引言

在 Brighton 海濱舉行的風大 10K 並不是測試比賽日裝備最溫和的地方，但這正是它有用的原因。當天氣與你作對時，你的跑鞋與手錶的優缺點就不再是抽象的理論，而是開始讓你付出時間的代價。這一次，有五件產品接受了完整測試：初代 Nike Alphafly、Alphafly 2、Vaporfly、Suunto Race 與 Polar Vantage V3。

比賽本身提供了大量素材。去程逆風，接著一段漫長的順風，然後從大約 5K 到剛過 9K 又是另一段磨人的逆風，最後是順風的快速收尾 800m。在這樣的賽道上配速確實很困難，而裝備必須在你不會主動選擇的條件下運作。

我們如何測試

Brighton 10K 沿著海濱進行，而當它不是 25mph 強風日時，它是一條好得離譜的賽道。路線在終點前包含一段短短的折返彎，讓你有一個目標可以瞄準，而不是一段直去直回的苦撐。當地其他賽事多半沿著海濱步道以繞圈方式進行，所以這個道路版本脫穎而出，是這一帶最棒的賽事之一，僅次於 Brighton Marathon Festival 10K。

不過，海岸的十一月是一場賭注。幾週前的另一場比賽風平浪靜；這一場則在大部分路線上直接吹向跑者、又從背後吹來。任何想在這裡嘗試刷新 PB 的人都該知道，風可以替你決定結果。

Nike Alphafly：依然特別

初代 Alphafly 當初是為馬拉松而買，後來在比賽日沒派上用場，如今結束退休生活，成為主要的訓練與比賽用鞋，而這些年來它依然表現出色。考量到之後問世的一波超級跑鞋，它依然輕得驚人，因為 Alphafly 3 與 Alphafly 2 都明顯比這個初代版本更重。

它最具代表性的特質就是彈力。順風奔跑時，這雙鞋滑順前行，而當你加速或追趕集團時，它會給你額外的推力與推進感，這是許多後續鞋款比不上的。相較於輕量、較高足跟差、更靈活的競速鞋，它用敏捷度換來飽滿、緩衝充足的腳感。而那正是後續款式所失去的敏捷度：Alphafly 2 更大、更彈，但在裡面用力踢腿——也就是你在側風中要接上集團時所需要的那種動作——會更費力。

據說新一代 Alphafly 即將推出，這個初代款式的供應正在縮減，這點值得在它完全消失之前記住。

Nike Alphafly 2：巨大、彈力十足、靈活度較低

The Alphafly 2 doubles down on the Alphafly concept. There is a lot of foam underfoot and a plush, energetic ride that feels almost like a hybrid of the Alphafly and its bigger sibling, springy in a way that makes long efforts feel cushioned and positive.

The trade-off is the same one noted above: the ride is big and bouncy, but the shoe does not have the nimble edge of the original. When you want to suddenly lift the pace and snap into a faster rhythm mid-race, the Alphafly 2 is slower to respond. For runners who prioritise maximum cushioning and bounce over sharpness, that is a comfortable compromise rather than a flaw.

It is also on the heavier side compared with the original, and it looks set to become cheaper once the next generation arrives and stock is cleared.

Nike Vaporfly：靈活的經典款

The Vaporfly keeps its place as the lighter, sharper option of the family. It is easy to turn the legs over in, sits a little more forward in its geometry, and suits runners who prefer a lightweight, quick-feeling racer over the bigger, boomier Alphafly approach.

It does not offer the same cloud of cushioning, and some runners will always prefer the Alphafly’s bouncier platform. But for surging, changing pace, and days when responsiveness matters more than padding, it remains a very compelling choice. Between the two models, the honest answer is that they reward different styles rather than one simply being better.

Suunto Race：表現出色，卻有一個難看時刻

In testing the Suunto Race has been genuinely excellent, close to earning a glowing review. It is part of a new wave of race watches that are clearly closing the gap on the market leaders, and on most training days it delivers everything you want from a modern GPS sports watch.

Race day, however, told a different story. Around 5K into the 10K it simply switched itself off and dropped back to the home screen, meaning the race went unrecorded at the moment it mattered most. One crash does not erase the strong testing record, but reliability is hard to review fairly when the failure happens on race day rather than on a training run. A full verdict needs more time and more races.

Polar Vantage V3：表現較好的一天

The Polar Vantage V3 has not been as consistently strong as the Suunto in general testing, and this was a second unit after the first one’s screen gave out and broke. Yet on this 10K it was the watch that behaved. It ran the full distance, logged the race distance accurately, and its lap markers came out essentially bang on, making it easy to pace with in tricky wind conditions.

Across two races on two watches, both had been excellent in training and both had failed on race day at least once. That is frustrating, but it also shows how close these brands now are to the established leaders: in training, both the Suunto Race and Polar Vantage V3 are genuinely competitive, and the gap is mostly about consistency on the days that count.

整體選購建議

If you want maximum bounce and cushioning in a supershoe, the Alphafly 2 delivers it in spades, but if you value a light, responsive ride and the ability to change pace instantly, the original Alphafly or the Vaporfly will suit you better, and the original is getting harder to find as a replacement approaches. On watches, the Suunto Race offers brilliant everyday performance with a question mark over race-day reliability, while the Polar Vantage V3 proved itself exactly where it counts in this test. Neither brand is quite at the consistency level of the market leader yet, but both are close.

Dress for the wind too. Layering wisely matters: a warm technical top without a base layer turned out to be the right call in changing conditions, while a dedicated winter racing base layer is better saved for genuinely cold days.

結論

The Brighton 10K rewarded kit that handles chaos: shoes that let you surge into a headwind and a watch that held its GPS through the whole route. The original Alphafly and the Polar Vantage V3 were the standouts of the day, while the Alphafly 2, Vaporfly and Suunto Race each showed their strengths elsewhere and their trade-offs on race morning. As always, the best gear is the gear that matches how you actually run.
