RIDERS REPORT
Insane climb
Completely brutal climb towards the end of Saturday's stage where nobody was talking to each other, followed by an insane descent that even the best off-road descenders were struggling with
First section off road
First section of off-road terrain that's quite greasy, requiring gravel tires
Prologue technical sections
5K prologue with pretty gnarly and technical sections like single track, described as hardcore with crazy climbs before, after and during them
First section off the road is quite greasy, requiring careful handling with gravel tires
Incredible trails through woods and around reservoirs that give an overwhelming sense of freedom, nothing like the technicality of the prologue
After dropping tire pressure to about 14 at the soup stop, the gravel runs a lot smoother

From the Field
The short 5K prologue section involves some pretty gnarly and some pretty technical sections and really showed what those amazing riders can do with their bikes.

Towards the end of Saturday's stage was an insane climb it was completely brutal and nobody was talking to each other and what followed was an insane descent even some of the best descenders I've seen off-road riders were really struggling with that.

RIDERS REPORT
Running Gravel King 650 by 48 tires on 650B wheels - not as quick as 700C but more insurance against things that go bump in the night
Six LEDs on handlebars with factory bag battery give really good vision even on low power because the light beams overlap, providing good contact for night sections
Dropped front tire pressure to about 14 at the soup stop which made the gravel run much smoother

Frequently Asked Questions
What is the climate like at Lauf Gritfest?
Historical weather data shows average highs of 62°F and lows of 48°F, with a 66% chance of rain on any given day. The 2022 forecast predicted 'torrential rain for the first 24 hours' and delivered — riders raced Saturday in full waterproofs after 'dry skies early on lulled riders into a false sense of security before the heavens opened.' More weather exposure than Belgian Waffle Ride San Diego.[2]
How are the logistics for Lauf Gritfest?
Registration Friday afternoon and Saturday morning, gates lock at 22:00, camping opens Friday noon. Mechanicals that 'put the overall out of reach' — plan your support accordingly in rural Carmarthenshire where backup options are thin. "With no phone signal at the campsite, the social side carries on into the evening, with people sitting around and sharing stories from the day. It feels more like a weekend away than a race weekend."[4]
How adventurous is Lauf Gritfest?
Three-day camping in the Cambrian Mountains with stages through remote terrain like Cwm Berwen. The final stage features 'a spectacular fast descent on a winding track through an old lead mine' with no chance to stop and appreciate it.[1]
How prestigious is Lauf Gritfest?
Elite riders like Emily Tillett compete here, but she won a stage while dealing with mechanicals — suggesting the field depth allows breakthrough performances. Seven editions deep, it's established regionally but lacks broader recognition.[8]
Should I race Lauf Gritfest?
If you're in the UK and want a Welsh mountain event—yes, it's solid. If you're international—there are better options.
