Gravel Locos

Free-to-enter Texas hill-country gravel — 150 miles, hot, dusty and grassroots.

Gravel

Character. A free-to-enter grassroots gravel race in the Texas hill country, run out of the small town of Hico. 150 miles, exposed and physically demanding, with a deliberately open entry policy.

Conditions. Central Texas in May is the wettest month of the local year, not a dry one: ~7.5 wet days and 8-9 thunderstorm days, both annual peaks, with roughly one day in four seeing rain (NOAA normals). Expect 28-30 °C and high humidity, and plan for either dust or mud.

Lube plan

If you wax — ZFC-recommended path. Heat-tolerant wax blend is the right preparation. Single pre-event application in the dry; carry Synergetic as emergency backup only for a sudden mid-route storm.

If you're on oil — pragmatic equivalent. A quality oil handles 150 miles of dry Texas gravel. Apply pre-event, carry a small bottle for the back half in the heat.

Long single-day in mixed weather — staged plan

Pre-wax with a top hot-melt the day before, then ride it through the whole event. If sustained heavy rain hits mid-ride, apply an oil over the wax and commit to a chain-stripper degrease at home before the next wax. Skip wax-emulsion drips for single-day events — they need 12+ hours to set hard, so they belong in a stage-race kit.

Skip wax-emulsion drips (SS Drip, UFO Drip v2) for single-day events — they need 12+ hours to set hard, so they belong in a stage-race kit. They'll do nothing useful in a single-day jersey.
Oil-rescue is the heavy lever — only pull it when conditions genuinely demand it (sustained heavy rain, long known wet sections). The moment you apply oil over wax you've committed to a chain-stripper solvent degrease before the next wax.
Critical: Do NOT apply grease or heavy wet oils (Muc-Off Hydrodynamic, WD-40, generic mechanic's oils) to a waxed chain. Those contaminate deeply and create a much harder reset than a clean wet-ride oil like Synergetic.
  1. 1
    Pre-event (24h+ before)
    Wax the chain with a top immersive hot-melt
    One application covers the whole event. Pick from the candidates below for the longest single-application life — a heat-tolerant base (Silca Endurance Chip) is worth adding if the day gets hot.
  2. 2
    Event start
    Start clean-waxed. Carry oil only if rain is forecast.
    Ride through passing showers — fresh wax handles them. The wax rinses and dries without meaningful contamination, and a slightly-rinsed wax costs less than the chain-stripper reset that comes with going oil-over-wax. Save the rain rescue for sustained heavy rain, not drizzle.
  3. 3
    Wet-day rescue (sustained heavy wet only)
    condition: sustained heavy rain or known long wet sections
    Apply an oil over the wax. Commit to a post-event degrease.
    Reserve this for conditions that genuinely demand it: Paris-Roubaix-grade wet, Lake District persistent rain, Iceland river crossings. Silca Synergetic over the top is ZFC's published rescue. Once applied, the chain returns to the wax pot only via a chain-stripper solvent degrease — that's the one route back.
  4. 4
    Post-event (only if an oil was applied)
    Chain-stripper solvent degrease, then re-wax
    Wet-weather oil behaves like factory grease. Use a proper chain stripper / solvent (mineral spirits, dedicated chain degreaser) with ultrasonic agitation — boiling water alone won't shift it. If the rain held off and you stayed on the wax, the chain goes straight back in the hot-melt pot for next time; no reset needed.

    Why this rank

    #1 because: mixed offroad riding gets a 20/40/40 split across clean, dry contamination, and wet contamination. Cyclowax Race Wax is eligible after scenario filtering and its wear (0.025) carried the most weight in its combined score, which — given your priority weights — edges out every other eligible lube.
