From the author's README on Thunderstore

Hoodlum Training Facility, brought to ReSkate from the original Skater XL map.

What's Changed

Scaled the map for ReSkate.
Added thickness to walls and roofs to block sunlight while preserving windows and openings.
Added ceiling lighting that stays on throughout the day and night.
Adjusted materials, decal transparency, and floor reflections.
Added grind splines.
Assigned surface sounds to match the map’s materials.
Reworked collision around the circular floor inset and raised manual pad to fix unwanted camera movement.

Install

Unzip the package and place the included map folder inside your Skate installation’s Mods folder. Restart ReSkate, then select HOODLUM TRAINING FACILTIY from the custom map menu.

Install HOODLUM TRAINING FACILITY

You need ReSkate and your own copy of skate. on Steam.

Open ReSkateLauncher.exe and go to MODS.
Search for HOODLUM TRAINING FACILITY and click install. The launcher also installs anything it depends on.
Press PLAY. In game, the MODS tab of the ReSkate menu (Insert) turns it on and off.

Or install it by hand: download the .zip and drop it on the launcher window, or unzip it into its own folder in Mods\ beside Skate.exe.

Maps show up in the ReSkate menu's level list. To join a server running a custom map, you need the same map installed. If the game won't load after installing, see known issues.

skatemods doesn't host or review this mod. The download comes straight from Thunderstore. Only install mods you trust, because scripts can run code.
